The difference and relation between complement and complement representation
Complemented code and one's complement code were the two ways to represent machine numbers in computers. There were differences and connections between the two. ** 1. The difference ** 1. ** It indicates the difference in form ** - ** Positive ** - For positive numbers, the form of the inverted code is the same as the original code. The highest bit is the sign bit (0 represents the positive number), and the rest of the bits are the numerical bits. For example, if the original code of a positive number was 0101 (assuming it was a 4-digit number), its complement would also be 0101. - The complement of a positive number is also the same as the original code. For example, if the original code is 0101, the complement is also 0101. - ** Negative ** - The complement of a negative number was represented by the sign bit of the highest bit being 1, and the rest of the digits were inverted based on the original code. For example, if the original code of an 8-digit-10 is 10001010, its complement is 11110101. - The complement of a negative number is the complement of a negative number plus 1. For-10, the complement of 11110101 plus 1 is 11110110. 2. ** Usage differences in computers ** - The complement code was usually used to find the complement code from the original code or to find the original code from the complement code. - In a computer system, values were all represented and stored in a complement code. This was because the use of a complement code allowed the sign bit and the value domain to be processed in unison, and addition and substitution could also be processed in unison. Furthermore, when the complement code and the original code were converted to each other, the operation process was the same, and no additional hardware circuits were needed. ** 2. Contact ** 1. ** Calculation Connection ** - For negative numbers, the complement was obtained by adding 1 to the complement. This was a very important connection between the two. For example, if the complement of a negative number was 1010 (assuming it was a 4-digit number), then its complement would be 1010 + 1 = 1011. 2. ** Change Contact ** - In the process of converting the original code and the complement code, the complement code played a role in the transition. When finding the complement from the original code, one could first find the complement, and then add 1 to the complement to get the complement. When finding the original code from the complement, one could first subtract 1 from the complement to get the complement, and then reverse the numerical bit of the complement to get the original code.

The representation and mutual conversion of the complement and the complement of the original code of truth value
1. ** True Value ** - The truth value was the true value represented by the machine number after removing the sign bit. For example, for the 8-digit machine number 10000011, the highest digit 1 represents negative, and its true value (true value) is-3, not the formal value 131 (10000011 converted to decimal equals 131). 2. ** Original Code ** - The original code was the way the computer stored a specific number. The first bit represented the symbol (0 plus 1 minus), and the other bits represented the absolute value of the truth value. For example, the original code of +11 was 00001011, and the original code of-11 was 10001011. If the original code of an 8-digit number was used to represent an integral number, the range of representation was-128 ~+127. The original code representation was simple and intuitive. During the multiplication operation, the mantissa was multiplied, and the sign bit was calculated separately. However, the sign value needed to be processed separately during the original code operation, which would make the logic circuit structure complicated. 3. ** Inverse code ** - For a positive number, its complement was the same as the original code. The highest bit was the sign bit (0 represented a positive number), and the rest of the digits were the same. For a negative number, the complement represented that the highest sign bit was 1, and the rest of the digits were reversed based on the original code. For example, an 8-digit number represented the decimal number-10, the original code was 10001010, and the complement code was 11110101. The complement code was usually used to find the complement code from the original code or to find the original code from the complement code. 4. ** Complement ** - In a computer system, numbers were always represented and stored in a complement. This was because the use of the complement code allowed the sign bit and the numerical domain to be processed in one place, and addition and substitution could also be processed in one place. Moreover, the process of converting the complement code to the original code was the same, and no additional hardware circuits were needed. For positive numbers, the complement is the same as the original code, and for negative numbers, the complement is based on the complement plus 1. For example, the decimal number-10, the original code is 10001010, the complement code is 11110101, and the complement code is 11110110. 5. ** Interconversion ** - ** Original code to inverted code **: The original code and inverted code of a positive number are the same. The inverted code of a negative number is based on the original code. The sign bit is kept unchanged, and the rest of the digits are inverted. - ** Original code to complement **: The original code of a positive number is the same as the complement; the complement of a negative number is obtained by first finding its complement (the sign bit is unchanged, and the rest of the bits are inverted), and then adding 1 to the complement. - ** Inverse code to original code **: The inverse code of a positive number is the same as the original code; the original code of a negative number is based on the inverse code, keeping the sign bit unchanged, and the rest of the numerical bits are inverted by bit. - ** Complement to Original Code **: The complement of a positive number is the same as the original code; the original code of a negative number is obtained by first calculating the complement minus 1 (the sign bit is unchanged, and the other bits are inverted), then the original code is obtained. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Calculating addition and deduction with complement and complement
In computers, symbolic numbers were represented in three ways: original code, complement code, and complement code. The complement code was mainly used to calculate the intermediate value of the complement code. For positive numbers, the original code, the complement, and the complement were the same. For negative numbers, the complement code meant that the sign bit of the original code was unchanged, and the rest of the bits were reversed. The complement code meant that the complement code was added with 1. When performing addition and substitution, the numbers in the computer were all represented and stored in the complement. This way, the sign bit and the numerical domain could be processed in one place, and addition and substitution could also be processed in one place. For example, calculate 1 - 1: 1. First, find the complement of 1 and-1. - The original code of 1 was [00000001]. Because it was a positive number, the complement was [00000001], and the complement was [00000001]. - The original code of-1 was [10000001], its complement was [11111110], and its complement was [11111111]. 2. Then, he added: - 1 - 1 was equivalent to 1+(-1), which was [00000001]+[11111111]=[0000000](This was the complement result). Because the complement of the result was [0000000], the corresponding original code was also [0000000], so the result was 0. For example, calculate 3 - 2: 1. Find the complement of 3 and-2: - The original code of 3 was [00000011], its complement was [00000011], and its complement was [00000011]. - The original code of-2 was [10000010], its complement was [11111101], and its complement was [11111110]. 2. Adding: - 3 - 2 was equivalent to 3+(-2), which was [00000011]+[11111110]=[00000001](complement result). The corresponding original code was also [0000001], and the result was 1. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Is 126 a complement?
126 itself was just an ordinary decimal number. In the computer, for signed numbers, original code, complement code, and complement code were different ways to represent numbers. If 126 was converted to an 8-bit binary-source code representation (because there was no word length specified, let's assume 8-bit as an example), the binary-source representation of 126 would be 0111110 (the original code, complement code, and complement code of positive numbers are the same). This could be seen as a representation of the number 126 in the computer (the original code form, also the complement code and complement code form, because it is a positive number). Therefore, it was not accurate to say that 126 was not a complement or a complement. 126 could be represented by the original code, the complement, and the complement. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Complement, complement, original code, code shift
In a computer, machine numbers had four forms of representation: original code, complement code, complement code, and code shift. The original code was the way the computer stored a specific number. It was composed of the sign bit plus the absolute value of the truth value. The first bit represented the sign (0 was positive, 1 was negative), and the remaining bits represented the absolute value of the truth value. The range of the number it represented was related to the number of digits (machine word length) of the binary-system. For example, the range of the original code of the 8-digit binary-system represented by the integral number was-128 to +127. It was more convenient for the original code to perform multiplication (mantissa multiplication, sign bit operation), but the operation of the symbol value needed to be handled separately, which would make the logic circuit structure complicated. The complement code was usually used to find the complement code from the original code or to find the original code from the complement code. For a positive number, its complement was the same as the original code. The highest bit was the sign bit (0 represented a positive number), and the rest of the digits were the same. For a negative number, the complement represented that the highest sign bit was 1, and the rest of the digits were reversed based on the original code. Complementing was also a way to represent signed numbers in a binary-code format. The complement of a positive number is the same as the original code, and the complement of a negative number is its complement plus 1. In a computer system, values were all represented and stored in a complementary code. This was because the use of a complementary code could unify the sign bit and the value domain, and addition and substitution could also be handled in a unified manner. Moreover, the complementary code and the original code were converted in the same way, and no additional hardware circuits were needed. The code shift was defined by adding an offset to the number X. It was often used to represent the order of a floating-point number. The definition of the code shift was: [X] shift = 2 ^n + X (-2^n <= X <= 2 ^n- 1, where n was the number of digits of an integral number). The main purpose of the code shift was to facilitate the comparison of sizes, because the larger the code shift, the corresponding truth value was also larger. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Original code, complement, and complement conversion device
Original code, complement code, and complement code were the two digits representation of numbers in computers. The conversion rules between them were as follows: * * 1. Transform the original code into the inverted code ** 1. * * Positive ** - Positive numbers have the same original code and inverted code. For example, the decimal number +5, if the original code was 00000101 in 8-digit binaries, its complement would also be 00000101. 2. * * Negative ** - For negative numbers, the sign bit (the highest bit) was kept unchanged, and the rest of the bits were inverted bitwise. For example, the decimal number-5, the original code of the 8-digit system was 10000101, and its complement was 11111010. * * 2. Reverse code to original code ** 1. * * Positive ** - Positive numbers had the same original code and inverted code, so they were directly the original code. 2. * * Negative ** - Keeping the sign bit unchanged, the rest of the bits can be inverted to obtain the original code. For example, if the complement was 11111010 (assuming it was an 8-digit number), then the original code would be 10000101. * * 3. Transform source code into complement code ** 1. * * Positive ** - The complement of a positive number is the same as the original code. For example, the 8-digit source code 00000111 for the decimal number +7, its complement is also 00000111. 2. * * Negative ** - First, the original code except for the sign bit was inverted to get the complement, then the complement was added by 1. For example, the decimal number-7, the original 8-digit bit code was 10000111, the first complement was 11111000, and then the 1 was added to get the complement 11111001. * * Four, convert complement to original code ** 1. * * Positive ** - The complement of a positive number was the same as the original code, and it was directly the original code. 2. * * Negative ** - Subtracting 1 from the complement to get the complement (if the highest bit after deducting 1 is 0, it has to be changed to 1 to maintain the representation of a negative number), then reversing the complement except for the sign bit to get the original code. For example, if the complement was 11111001 (an 8-digit number), then minus 1 to get 11111000 (this was the complement code), and then negating it to get the original code 10000111. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
How does a complement and a negative become a complement?
The way to turn a complement negative into a complement was to subtract 1. For example, if the complement of a negative number was 1111011, then minus 1 would give 11111010, which was the corresponding complement. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Original code complement and complement operation rule table
1. ** Original Code ** - [Description: The original code is the absolute value of the sign bit plus the truth value. The first bit represents the sign (0 represents a positive number, 1 represents a negative number), and the remaining bits represent the value.] For example, in an 8-bit system,(+1)(original code)= 0000001,(-1)(original code)= 1000001. The value range of the original code of an 8-bit number is (-127, 127). - [Calculation: Original code is the representation that is easiest to understand and calculate by the human brain. The calculation follows the conventional addition and deduction rules, but the symbol bit needs to be dealt with separately.] 2. ** Inverse code ** - [Description: The complement of a positive number is itself, and the complement of a negative number is based on the original code. The sign bit is unchanged, and the other bits are inverted.] For example,(+1) = (00000001)(original code)=(00000001)(inverted code),(-1)=(10000001)(original code)=(11111110)(inverted code). - [Calculation: When performing calculations, the original code needs to be converted into the inverted code first, and then the calculation is carried out according to the rules. The calculation result may need to be converted back to the original code to obtain an intuitive value.] 3. ** Complement ** - [Description: The complement of a positive number is itself, and the complement of a negative number is based on the original code. The sign bit is unchanged, and the other bits are inverted. Finally,+1 (that is,+1 on the basis of the complement code).] For example,(+1)=(00000001)(original code)=(00000001)(complement)=(00000001)(complement),(-1)=(10000001)(original code)=(11111110)(complement)=(11111111)(complement). For-128, the original code was 10000000, the complement was 1111111, and the complement was 10000000. - [Operations: Negative numbers are represented by the complement in computers. When performing numerical operations, the complement is directly used to perform the operation. The result is also in the form of the complement. If you want to obtain an intuitive numerical result, you may need to convert the complement into the original code.] <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
+13 and 13's complement
In a computer, if it was expressed as an 8-digit number: 1. ** Original Code **: - For +13, because the highest bit of the original code of a positive number was 0, the rest of the digits were the absolute value of the truth value. 13 was represented as 1101, so the original code of +13 was 00001101. - Since 13 was +13, its original code was also 00001101. 2. ** Inverse **: - The complement of a positive number was the same as the original code, so the 8-digit complement of +13 and 13 were both 00001101. 3. ** Complement **: - The complement of a positive number is the same as the original code, so the 8-bit complement of +13 and +13 are both 00001101. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
1's complement
If it was expressed in 8-bit binaries: - [Original code: Because 1 is a positive number, the highest bit of the original code is 0, which represents a positive number. The rest of the digits are numerical digits. The 8-bit original code of 1 is 0000001.] - Inverse code: The inverse code of a positive number is the same as the original code, so the inverse code of 1 is 0000001. - Complement: The complement of a positive number is the same as the original code, so the complement of 1 is 0000001. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Complement Company Journey
There are many forms and purposes for a company trip. Here are some supplements: ** I. Journey to the company from an investor's perspective ** 1. ** Ping An Security's Journey of Value Discovering for a Public Company ** - Ping An Security launched a journey of value discovery for listed companies, such as entering Citic Haizhi at the Shenzhen-based station. This event invited high-net-worth clients to participate, and clients could gain an in-depth understanding of the industrial layout and investment value of listed companies. During the event, customers could communicate face-to-face with corporate executives and experience the company's products and services, which would help investors make secondary market investment decisions. Through such activities, Ping An was committed to maintaining and increasing the value of its clients 'wealth and becoming a professional consultant for long-term value investments. 2. ** Impact on enterprise valuation ** - For investors, the company tour provided an opportunity to gain an in-depth understanding of the actual situation of the company's operations. In traditional investment analysis, investors often relied on written information such as financial statements, but field visits could discover the actual advantages and potential problems of the company in production, management, market expansion, and so on. For example, in the process of visiting the company, investors could intuitively feel its layout in the low-altitude economic field, assess its competitiveness in the industry, and more accurately determine the investment value of the company. ** II. Company journey from the perspective of enterprise cooperation and business expansion ** 1. ** Project Cooperation in Business Exploration Journey ** - For example, in Almaty's business project introduction, this could be seen as a special business exploration journey. Some entrepreneurs discovered that there were projects with rich land resources, complete construction facilities, and a good ecological environment, including two buildings, 90 acres of land, more than 100 rooms, and an area of more than 6,000 square meters. Such a project could attract companies or individuals who had the intention to cooperate and develop it together through resource sharing and win-win cooperation. For example, it could be developed into an eco-tourism project, using local grasslands, mountains, rivers, ecological lakes, and other resources to carry out horse-riding and other tourism activities. It could also transform the hall inside the building and develop suitable commercial projects according to its height of more than eight meters. 2. ** Company trip related to the company's sea trip ** - Many enterprises participated in the research and learning journey of the specialized and new salons and the digital benchmark enterprises of Skyworth. This event was not only a sharing of knowledge and experience, but also an opportunity for companies to think and explore about going out to sea. The companies faced challenges such as digital technology competition, diverse market demands, and trade sanctions. In such a company journey, business leaders could exchange countermeasures, such as Chairman Wang's suggestions for enterprises to establish digital thinking and find digital platforms to cope with the digital wave; the founder of Skyworth Group shared his experience in understanding the local market and improving the language level. Chairman Dickson shared his successful experience from the perspective of professional sea service and analyzed the global strategy from a business perspective. - The "China Technology Journey" of the Northern European entrepreneur delegation to visit and exchange at the headquarters of Byd was also a manifestation of mutual learning and cooperation opportunities between enterprises. By demonstrating its technological innovation, such as its achievements in the field of new energy vehicles (one out of every five new energy vehicles sold in the world, there was one Byd), it demonstrated its strength to foreign entrepreneurs and sought to promote its technological achievements to the global market as well as possible cooperation opportunities. ** 3. A company journey from the perspective of a job seeker ** 1. ** The value of a career journey ** - The "Blue Collar Home" in Hangu Town, Chongqing High-tech Zone, Western Science City, launched a career exploration tour for unemployed college graduates, unemployed people, and other people who were willing to work. When the job seeker visited the company, he could gain an in-depth understanding of the company's office environment, accommodation conditions, production workshops, corporate culture, product types, sales channels, production processes, etc. He could also communicate with the company on working hours, benefits, and other issues. The company could also provide different types of positions for job applicants to choose from. This process could increase the success rate of job hunting and also help the company recruit suitable employees. For job applicants, this was a way to understand the company intuitively. It was more comprehensive and in-depth than just looking at the recruitment information. The novel,"The Couple's Universe: The Amazing Legend of Shen Zhen" is equally exciting.
