Enum Rounding 

pub enum Rounding {
    Nearest,
    TowardZero,
    TowardPlusInf,
    TowardMinusInf,
}

The rounding mode from FCSR.RM (UM §7.2.4).

Variants

Nearest

Round to nearest, ties to even. The IEEE default and FCSR.RM = 0.

TowardZero

Toward zero (truncate).

TowardPlusInf

Toward +∞.

TowardMinusInf

Toward −∞.

Implementations

impl Rounding

pub const fn from_rm(rm: u8) -> Self

Decode FCSR.RM (bits 1..=0).

Trait Implementations

impl Clone for Rounding

fn clone(&self) -> Rounding

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Rounding

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Rounding

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for Rounding

fn eq(&self, other: &Rounding) -> 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 Serialize for Rounding

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Copy for Rounding

impl Eq for Rounding

impl StructuralPartialEq for Rounding
