Two's Complement Calculator

Two's complement 1. In computer systems, numbers are always represented (stored) in two's complement. The main reason: using two's complement, the sign bit and other bits can be processed uniformly; at the same time, subtraction can also be processed as addition. In addition, when two numbers represented in two's complement are added, if the highest bit (sign bit) has a carry, the carry is discarded. 2. The conversion process of two's complement and original code is almost the same.

For example

1111 1111 255
− 0101 1111 − 95
=========== =====
1010 0000 (ones' complement) 160
+ 1 + 1
=========== =====
1010 0001 (two's complement) 161
