Enum RoundingMode 

pub enum RoundingMode {
    HalfEven,
    HalfAway,
    HalfToZero,
    ToZero,
    ToInf,
    ToNegInf,
    AwayFromZero,
}

Rounding modes for native BigFloat arithmetic.

Mirrors the set of rounding policies natively supported by the binary BigFloat core. The seven variants cover all IEEE-754 directed and nearest-tie-break combinations.

Variants

HalfEven

Round half to even (banker’s rounding).

HalfAway

Round half away from zero.

HalfToZero

Round half toward zero (truncate ties).

ToZero

Truncate toward zero (drop fractional bits).

ToInf

Round toward +∞.

ToNegInf

Round toward -∞.

AwayFromZero

Round away from zero (round up in magnitude).

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 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.
