Arithmetic left shift operatorIn binary form, all numbers are shifted to the left by the corresponding number of digits, the high position is removed (discarded), and the low vacancy is 0. syntax format: Number of shifts required for numbers
1. Arithmetic left shift logic left
The arithmetic left shift and the logical left shift are the right 0:
Like 00101011.
Shift arithmetic left one: 01010110
Shift logic left one: 01010110
For binary values, the left-shift n-bit equals the
Arithmetic left shift operator>> operation rules:according to the binary form to move all the numbers to the right of the towering digits, low-shifted out (discard), high position of the vacancy complement the sign, that is, positive 0, negative
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

About the shift left operator in C language, the shift left Operator
Referring to c and pointer, the result of left shifting in c language is the same regardless of arithmetic or logical left shifting. In addition, perform the same operation for the
The shift operator is also for the binary "bit", which mainly includes the left shift operator (>>), and the signed right shift operator (>>).
1. Left shift operatorThe left-shift operator, represented by "public class Data17{public static void
Both the left and right shifts are the concepts of bit operations. We know that computers store data based on binary, so the concept of left and right shifts is important. This article deals with a 32-bit machine. [left] discard highest bit, 0
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
Let's say move left, move left to shift all bits of a number to the left, and in C with the int i = 1;i = i In other words, 1 of the 2 binary is 000 ... 0001 (here 1 the number of front 0 is related to the number of int, 32-bit machine, GCC has 31 0)
