Offset binary

Offset binary, also known as "biased binary" or "excess-N" representation, is a binary number encoding system that is primarily used to represent signed integers in a way that makes certain arithmetic operations simpler, particularly in digital electronics. In offset binary, a bias value is added to the actual value being represented to compute its binary equivalent. For example, in an n-bit offset binary system, the bias is typically \( 2^{(n - 1)} \).
