Enum RoundingMode 

#[non_exhaustive]
pub enum RoundingMode {
    Ceil,
    Floor,
    Expand,
    Trunc,
    HalfCeil,
    HalfFloor,
    HalfExpand,
    HalfTrunc,
    HalfEven,
}

roundingMode (ECMA-402’s names and meanings).

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Ceil

ceil: towards +∞.

Floor

floor: towards −∞.

Expand

expand: away from 0.

Trunc

trunc: towards 0.

HalfCeil

halfCeil: to the nearest, ties towards +∞.

HalfFloor

halfFloor: to the nearest, ties towards −∞.

HalfExpand

halfExpand (the default): to the nearest, ties away from 0.

HalfTrunc

halfTrunc: to the nearest, ties towards 0.

HalfEven

halfEven: to the nearest, ties to even.
