Sign (mathematics)

number property of being positive or negative

mathematical symbol: ±

mathematical symbols used to represent the notions of positive and negative as well as the operations of addition and subtraction; mathematical symbols that specify sign of a number

zero with an associated sign

displacement measured angle-wise when a body is showing circular or rotational motion

group homomorphism from the symmetric group over a finite set to the two-element group {±1}

generalized notion of measure in mathematics

bit indicating the sign of a number

distance from a point to the boundary of a set

In computing, signedness is a property of data types representing numbers in computer programs. A numeric variable is signed if it can represent both positive and negative numbers, and unsigned if it can only represent non-negative numbers (zero or positive numbers).

positional numeral system with signed digits; the representation may not be unique
