difference between arithmetic shift and logical shift

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

The right and left shifts are different. For the left, there is no "logical left" and "arithmetic left" the difference, the main difference here is the computer system according to the highest bit (that is, sign bit) is "1" or "0", supplementing "1"

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

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 ------------------------------------------------------

One, Java bit operation1. Presentation method:In the Java language, the binary number is represented by a complement, the highest bit is the sign bit, the sign bit for positive numbers is 0, and the negative is 1. The complement representation needs

bit arithmeticThe operation component of a bitwise operation can only be integer or character data, and the bitwise operation considers the operand as a bit string information composed of binary bits, and completes the specified operation by bit,
