2s (Twos) Complement Discussion.
1’s Complement discussion from here.
2’s complement of a binary number N is obtained by the formula (2^n) – N
, Where n is the no of bits in number N
Example: Convert binary number 111001101 to 2’s complement.
Method: 2’s complement of a binary no can be obtained by two step process
Step 1: 1s complement of number N = 000110010
Step 2: 1’s complement + 1
000110010
+ 000000001
= 000110011
Answer: 2’s complement of a binary no 111001101 is 000110011
