---------------------1. Concept of Modulo (I will only give an example to illustrate how to look up the concept of "same-modulus" in mathematics ")In daily life, there are many examples of subtraction and addition. For example, the clock runs at 12 bits, and can also be regarded as zero.There are two ways to adjust the hour hand from 10 to 5:1. Set the clockwise direction to 5 cells, which is equivalent to subtraction: 10
Java constructs static code blocks for common code blocks and static code blocks.
1. Common Code Block
Public static void main (String [] args ){/* Common Code block:* A code block is directly defined as a normal
I. For positive numbers, the original code and the reverse code are the same, and all are positive numbers. For negative numbers, the original code is the binary value of the absolute value of X when the symbol bit is 1. The anti-code is that the symbol bit is 1, and the other bit is the reverse of the original

But also because it is too small, its information capacity is limited, DM can not express Chinese characters and other forms, and QR code to use data compression method to express Chinese characters, only 13bit can represent a Chinese character, co
I. Definition1. Original codeThe positive sign bit is 0, and the negative sign bit is 1. The other bits represent the absolute value of the number according to the general method. In this way, the original code of the number is obtained.[Example 2.13] when the machine word length is 8-bit binary:X = + 1011011 [x] source code = 01011011Y = + 1011011 [y] source code
1. Representation of the source code, reverse code, and complement code
(1) original code: directly add a sign before the value.
For example, the symbol bit value
[+ 7] original = 0 0000111 B
[-7] original = 1 0000111 B
Note: a. The original code of the number 0 has two
We all know that data is stored in bytes in the computer. one byte equals 8 bits (1 byte = 8 bits), while the computer can only recognize the numbers 0 and 1, therefore, according to the arrangement, energy saving for one word represents 256 different types of information, that is, 28 (0 and 1 are two possibilities, and 8 bits are arranged ), for example, to define an unsigned integer (unsigned char) of the byte size, it can represent 0 ~ 255 (0 ~ 28-1) these numbers are 256 in total, because, a
Original code: converts an integer to a binary value, which is the original code. For example, the original code of 5 in a single byte is 0000 0101, and the original code of-5 is 1000 0101.Reverse code: the reverse code of a posit

I. Definition of the original code
The original, reverse, and supplementary codes are Binary Fixed-point representation of numbers in the computer.
The highest bit of the original code representation is the sign bit. 0 indicates positive, and 1 indicates negative. The specific definitions are divided into decimals and positive numbers. Here we will only discuss the definitions of integers:
Assume that one b

complement code can be used to process the symbol bit and other digits in a unified manner. At the same time, the subtraction can also be processed by addition. The other two are supplemented.If the highest bit (symbol bit) has a forward bit, the carry is discarded.The conversion process of the complement code is almost the same as that of the original code.The value complement representation is also divid
Guide:GitHub is a well-known platform for it enthusiasts to share code, and it's popular, how do we usually upload our own code to GitHub to save it and provide it to others for reference?I think there are several ways to do this:1, upload the code directly on the GitHub Web page (not tried);2, using git tools, download git and then use command-line tools to uplo
