Enum RoundingMode 

pub enum RoundingMode {
    Nearest,
    TowardZero,
    TowardPositive,
    TowardNegative,
    AwayFromZero,
}

A rounding direction for a floating-point result, following IEEE 754 and MPFR.

Variants

Nearest

Round to the nearest representable value; ties to even. The default.

TowardZero

Round toward zero (truncate).

TowardPositive

Round toward positive infinity (ceiling).

TowardNegative

Round toward negative infinity (floor).

AwayFromZero

Round away from zero.

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 Copy for RoundingMode

impl Debug for RoundingMode

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

Formats the value using the given formatter.

impl Default for RoundingMode

fn default() -> RoundingMode

Returns the “default value” for a type.

impl Eq for RoundingMode

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.
