I. Concept of Modulo (I will only list one example. For details, refer to "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:
Ii. Use of the modulo (using the modulo to obtain the complement code)1,The following code is obtained:To convert
Guiding Ideology: implement logical separation between new code and bad code. This is only to write unit tests for new code and implement TDD, without having to write unit tests for bad code.
Method 1 (when the responsibilities of the new Code are significantly different fr
What is a number system? Rules used to represent numeric values, such as decimal and binary.
Machine count
Represents a number in binary format. The highest digit is the sign bit. 1 indicates a negative number, and 0 indicates a positive number.
For example: 1 ----> 00000001;-1 ----> 1000 0001True Value
We can see from the above that the number of machines is a form of computer used to represent the number, but the maximum bit is a symbol. In this case, 1000 0001 represents 1 rather than 129. In
The previous blog briefly introduced the computer Central Plains code, back code, complement and shift code representation (http://blog.csdn.net/xdd19910505/article/details/40424533), for the computer why it is not very clear, it seems to know such a thing, but I don't know why. It's like a person you don't know, he's not his friend, you don't know what he's ....

One: Ordinary code block1 //Ordinary code block: {} that appears in a method or statement is called a normal code block . ordinary blocks of code and general execution order of statements are determined by the order in which they appear in the code-"first Occurrence first" 2
The Code 39 code rules are:1, each five line represents a character;2, The thick line is 1, the thin wire represents 0;3, the gap between lines of the width of the expression 1, a narrow representation of 0;4, five lines plus the four gap between them is nine-bit binary encoding, and this nine bit must have three bits is 1, so called 39 yards;5, the first and last of the bar
Why?
The computer uses binary to represent a value. For example, decimal number 10 is expressed as 1010 in binary number. Set the computer to 8 characters, that is, 1 byte. The highest digit indicates the symbol. 0 is positive and 1 is negative.Let's take a look at the problems with the addition, subtraction, multiplication, division, and number represented by the original code:
Decimal: 1-1 = 1 + (-1) = 0

Values have positive and negative values, and the computer uses the highest bit of a number to store the symbols (0 is positive, 1 is negative ). this is the original code of the number of machines. assume that the number of digits processed by the machine is 8. that is, the word length is 1 byte, and the original code can indicate the value range is 127 ~ (-127)Source
