Interactive FAQ
What is the range of numbers that can be represented using 2’s complement?
The range of numbers that can be represented using n-bit 2’s complement is -2^(n-1) to 2^(n-1) – 1.
How does 2’s complement differ from sign-magnitude representation?
2’s complement is more efficient than sign-magnitude representation as it uses one bit less to represent negative numbers.
