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
