Enum RoundingMode

pub enum RoundingMode {
    HalfToEven,
    HalfAwayFromZero,
    HalfTowardZero,
    TowardZero,
    AwayFromZero,
    ToNegativeInfinity,
    ToInfinity,
}

Rounding modes to be used by FloatLike types.

Variants

HalfToEven

“Bankers Rounding” Rounds .5 to the nearest even number, typical rounding behavior otherwise. e.g. 2.5 becomes 2, 3.5 becomes 4.

HalfAwayFromZero

Rounds .5 away from zero (typical rounding behavior). e.g. 2.5 becomes 3, -2.5 becomes -3.

HalfTowardZero

Rounds .5 towards zero. e.g. 2.5 becomes 2, -2.5 becomes -2.

TowardZero

Rounds towards zero (typical round down). e.g. 2.7 becomes 2, -2.7 becomes -2.

AwayFromZero

Rounds towards negative/positive infinity (typical round up). e.g. 2.3 becomes 3, -2.3 becomes -3.

ToNegativeInfinity

Rounds towards negative infinity (round positive numbers down and negative numbers “up”). e.g. 2.7 becomes 2, -2.3 becomes -3.

ToInfinity

Rounds towards positive infinity (round positive numbers up and negative numbers “down”). e.g. 2.3 becomes 3, -2.7 becomes -2.

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 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.

impl Copy for RoundingMode

impl Eq for RoundingMode
