Enum RoundingMode 

pub enum RoundingMode {
    HalfEven,
    HalfAwayFromZero,
    TowardZero,
    Floor,
    Ceiling,
}

Rounding modes for explicit quantization and context rounding.

Variants

HalfEven

Round to nearest; ties to even last digit.

HalfAwayFromZero

Round to nearest; ties away from zero.

TowardZero

Truncate toward zero.

Floor

Round toward negative infinity.

Ceiling

Round toward positive infinity.
