# Twos Complement Converter

This is a decimal/binary to two’s complement converter and a two’s complement to decimal converter. It is a system in which the negative numbers are represented by the two’s complement of the absolute value.
For example : -9 converts to 11110111 (to 8 bits), which is -9 in two’s complement.
Complementing it would make it 9, or 00001001 to 8 bits.

Step 1: Begin with the binary value
10011001
Step 2: Formed the one's complement as follows:
01100110
Step 3: Add 1 to the one's complement
