pub struct RoundingMode(_);
Available on AArch64 only.
Expand description

Floating-point rounding mode, as defined by IEEE 754.

Implementations§

source§

impl RoundingMode

source

pub const Nearest: Self = _

Round to the nearest number, with ties toward even numbers.

source

pub const PlusInfinity: Self = _

Round toward positive infinity.

source

pub const MinusInfinity: Self = _

Round toward negative infinity.

source

pub const Zero: Self = _

Round toward zero (truncate).

source

pub const fn name(self) -> Option<&'static str>

The name of the enum variant in code, if one is defined for this value.

An identical method is available through the CEnum trait, but this version is declared const (which is currently unstable on traits).
