In computer science, the sign bit is a bit (usually the most significant bit) in a computer numbering format that indicates the sign of a number. Typically, if the sign bit is 1, the number is negative (for two's complement integers) or non-positive (for ones' complement integers, sign-magnitude integers, and floating point numbers), and 0 indicates a positive number.
