Enum RoundingStrategy 

pub enum RoundingStrategy {
    MidpointAwayFromZero,
    MidpointToEven,
    Ceiling,
    Floor,
    Truncate,
}

Explicit rounding strategy. Always required — no hidden defaults.

Variants

MidpointAwayFromZero

Rounds midpoint 0.5 away from zero (also known as commercial or half-up rounding). The most common choice for invoicing.

MidpointToEven

Rounds midpoint 0.5 to the nearest even digit (banker’s rounding). Minimises cumulative rounding bias over many operations.

Ceiling

Always round toward positive infinity.

Floor

Always round toward negative infinity.

Truncate

Truncate toward zero (discard fractional digits).
