Enum RoundingMode 

pub enum RoundingMode {
    Up,
    Down,
    Ceiling,
    Floor,
    HalfUp,
    HalfDown,
    HalfEven,
    Unnecessary,
}

Rounding modes for arbitrary-precision arithmetic.

This enum is independent of any backend library and provides a common vocabulary for precision control across all OxiNum numeric types.

Variants

Up

Round toward positive infinity.

Down

Round toward negative infinity.

Ceiling

Round toward positive infinity (alias for Up in unsigned context).

Floor

Round toward negative infinity (alias for Down in unsigned context).

HalfUp

Round half toward positive infinity.

HalfDown

Round half toward negative infinity.

HalfEven

Round half to the nearest even digit (banker’s rounding).

Unnecessary

Exact result required – error if rounding would occur.

Trait Implementations

impl Clone for RoundingMode

fn clone(&self) -> RoundingMode

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for RoundingMode

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Display for RoundingMode

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Hash for RoundingMode

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for RoundingMode

fn eq(&self, other: &RoundingMode) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
