= 1 + (-1) = [0000 0001] Original + [1000 0001] original = [0000 0001] Anti + [1111 1110] anti = [1111 1111] reverse = [1000 0000] Original = 0 It is found that the true value of the result is correct by inverse code calculation and subtraction. The only problem is in the "0" of this particular value. Although it is understood that +0 and 0 are the same, the 0 notation does not make any sense. And there will be [0000 0000] Original and [1000 0000] The original two codes represent 0.So the

and two coding problems: 1-1 = 1 + (-1) = [0000 0001] Original + [1000 0001] the original = [0000 0001] Complement + [1111 1111] complement = [0000 0000] Complement =[0000 0000] Original So 0 is represented by [0000 0000], and 0 of the previous problem does not exist. And can be represented by [1000 0000]-128: (-1) + (-127) = [1000 0001] Original + [1111 1111] original = [1111 1111] complement + [1000 0001] complement = [1000 0000]

Analysis of id3v1 information and ID3v2 information structure of MP3 files -- Wu Juntao 2005/05/05 E-mail: bo_tao@126.com QQ: 29248671 Main Page: http://wjt276.home4u.china.com (with source code) I am a programmer and want to use VB. NET to write a program that can read information about MP3 files, but does not know the file structure. Ah, I have been online for a long time (for several months) and have not found VB. Later I saw a VC with a structure analysis. That's great. I. Analysis of "ID3

weight is also the highest (for the number of 1 byte is 2 to the power of 7 = 128), so only less than one bit, the maximum value is halved at once. However, the advantage of a signed number is that it can represent a negative number. Therefore, although it has shrunk in the maximum value, it is stretched in the negative direction. We still compare the values of one byte: Unsigned number: 0 --------------- 255 Signed quantity:-

in the computer, negative numbers are expressed in the complement. Why not just use the original code to express. such as single byte -5:1000 0101. I want to consider the software for two reasons: 1, representing the range of single-byte integers, the unsigned type, which represents a range of [0,255], representing a total of 256 data. A signed type whose representation range is [-128,127]. Look at unsigned first, 0 means 0000 0000,255 is 1111 1111, just meet the requirements, can represent 25

In our daily development, manipulating and converting arrays is a very common operation, let's look at an example:The code is as follows:var descolors = [],Srccolors = [{r:255, g:255, b:255},//White{r:128, g:128, b:128},//Gray{r:0, g:0, b:0}//Black];for (var i = 0, Ilen = srccolors.length; i var color = Srccolors[i],format = function (color) {Return Math.Round (C

When learning the essence of C language complement code (http://learn.akae.cn/media/ch14s03.html ). It is not very understandable, especially the description section. If 8 bits use the 2's sComplement notation, The value range of negative numbers is from 10000000 to 11111111 (-128 ~ -1 ), Positive numbers are from 00000000 to 01111111 (0 ~ 127 ). So I searched a lot of materials and finally clarified this point. First, the original code, the anticode,
