Enum RoundingDirection 

pub enum RoundingDirection {
    ToZero,
    AwayZero,
    ToEven,
    ToOdd,
}

Directed rounding.

We can translate sign of an unrounded number and a RoundingMode, into a RoundingDirection and a boolean indicating if the direction should only be used for tie-breaking (see RoundingMode::to_direction). It is usually easier to implement rounding using the latter pair of values.

Variants

ToZero

Rounds to the closest representable value with smaller (or same) magnitude.

AwayZero

Rounds to the closest representable value with greater (or same) magnitude.

ToEven

Rounds to the closest representable value whose mantissa has a least significant bit of 0.

ToOdd

Rounds to the closest representable value whose mantissa has a least significant bit of 1.
