Binary 2’s Complement

Compute the 2’s complement representation and conversions.

Example: 1010

Definition: Computes the two's complement representation for signed binary numbers and performs related conversions.

Conversion

Two's complement (N-bit signed): if MSB=0 value = unsigned; if MSB=1 value = unsigned - 2^N.
To compute negative: invert bits and add 1.
Example (4-bit): 1011 → invert 0100 + 1 = 0101 → value = -5
