Frequently Asked Questions
Two's complement is a way to represent signed integers in binary. It is the most common method for representing negative numbers in computer systems.
First, write the absolute value in binary. Then invert all bits (change 0 to 1 and 1 to 0). Finally, add 1 to the inverted binary number.
For 8-bit two's complement, the range is -128 to 127.
