Directory Introduction Original code Reverse code Complement Why is the 8-bit binary number in the range of-128 ~ + 127? Introduction The number of symbols in a computer has three Representation Methods:Original code,Reverse codeAndComplement. All three representation methods are available.Symbol bitAndNumeric bitIn the two parts, the symbol bits are expres

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

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

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 Original

Recently reported a soft test, the basic knowledge of evil, the previous learned the original code, anti-code, the complement unexpectedly forget, there are not familiar with the shift code, deliberately spend some time to organize, hope to help everyone. Concept Introduction:The information in the computer is expressed in binary form, the value is positive or
