arithmetic shift operations

The shift operation of C language is one of the most frequent operations that programmers use every day, and the shift operation can save us a lot of time and the program can be written more beautifully. We say that the shift operation can be

Big integer algorithm [05] shift operation, integer 05 In the previous blog post, we talked about operations related to the entire number of digits. This time the content is still related to bit operations: shift operations. It should be noted that

Our common shift operations are >, which are left-and right -shifted respectively. There are two kinds of arithmetic shift and logical shift in C language. The difference between >> and >>> in JS ------------------------------------------------------

1. arithmetic operation points (1) shift operation ① Original code shift: the original code does not change the form of the original code when performing arithmetic shift left or arithmetic shift right. Shifts one digit to the left is equal to

Note: This article is excerpted from Chapter 2 "deep understanding of computer systems.Shift operation: The C language also provides a set of shift operations to move the bit to the left or right. For a single digit expressed as [xn-1, xn-2 ,..., X0]

On most machines, the division of integers is slow and requires more than 30 clock cycles, divided by the power of 2, and can be implemented with shift operations. Code on first #include "stdio.h"int main (){int x=-128;int Y=X/4;printf ("y=%d", y);}

  Complement and arithmetic right shift command Supplemental Discussion The advantage of complement makes the original code with the highest bit redundant. A positive complement is itself, and a negative complement is obtained by completing its

1. Left shift operatorThe left shift operator 1) Its general format is as follows:Value NUM Specifies the number of bits to shift the value to move.Left-shift rule remembers only one point: Discard the highest bit, 0 the minimum bitIf the number of
