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 complement appeared, solved 0 symbols and two coding problems: 1-1 = 1 + (-1) = [0000 0001] Original + [1000 0001] original = [0000 0001] Complement + [1111 1111] complement = [0000 0000] Complement =[0000 0000] Original So 0 is denoted by [0000 0000], and 0 of the previous problem does not exist.

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.

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
