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

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
