Enum fixed_decimal::signum::Signum

pub enum Signum {
    BelowZero,
    NegativeZero,
    PositiveZero,
    AboveZero,
}

Return value of the sign function for FixedDecimal, indicating the sign of the number as well as whether the number is nonzero.

Unlike the mathematical sign function sgn, the FixedDecimal sign function distinguishes between positive and negative zero, since in computing, the sign bit is orthogonal to the magnitude of the numerical value.

Variants

BelowZero

A negative, nonzero value.

NegativeZero

A zero value with the sign bit set.

PositiveZero

A zero value without the sign bit.

AboveZero

A positive, nonzero value.
