Enum BinaryNaNPropagationMode

#[repr(u8)]
pub enum BinaryNaNPropagationMode {
    AlwaysCanonical = 0,
    FirstSecond = 1,
    SecondFirst = 2,
    FirstSecondPreferringSNaN = 3,

}

Select how NaN payloads should be propagated

Variants

AlwaysCanonical = 0

NaN payloads are always canonical

FirstSecond = 1

If the first argument is a NaN, then the result uses the first argument’s payload, else if the second argument is a NaN, then the result uses the second argument’s payload, else the result is the canonical NaN.

SecondFirst = 2

If the second argument is a NaN, then the result uses the second argument’s payload, else if the first argument is a NaN, then the result uses the first argument’s payload, else the result is the canonical NaN.

FirstSecondPreferringSNaN = 3

If the first argument is a signaling NaN, then the result uses the first argument’s payload, else if the second argument is a signaling NaN, then the result uses the second argument’s payload, else if the first argument is a NaN, then the result uses the first argument’s payload, else if the second argument is a NaN, then the result uses the second argument’s payload, else the result is the canonical NaN.

SecondFirstPreferringSNaN = 4

If the second argument is a signaling NaN, then the result uses the second argument’s payload, else if the first argument is a signaling NaN, then the result uses the first argument’s payload, else if the second argument is a NaN, then the result uses the second argument’s payload, else if the first argument is a NaN, then the result uses the first argument’s payload, else the result is the canonical NaN.

Implementations

impl BinaryNaNPropagationMode

pub fn calculate_propagation_results( self, first_class: FloatClass, second_class: FloatClass, ) -> BinaryNaNPropagationResults

calculate the result of NaN propagation for a floating-point operation

Trait Implementations

impl Clone for BinaryNaNPropagationMode

fn clone(&self) -> BinaryNaNPropagationMode

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for BinaryNaNPropagationMode

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

Formats the value using the given formatter.

impl From<BinaryNaNPropagationMode> for UnaryNaNPropagationMode

fn from(v: BinaryNaNPropagationMode) -> Self

Converts to this type from the input type.

impl From<TernaryNaNPropagationMode> for BinaryNaNPropagationMode

fn from(v: TernaryNaNPropagationMode) -> Self

Converts to this type from the input type.

impl Hash for BinaryNaNPropagationMode

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 BinaryNaNPropagationMode

fn eq(&self, other: &BinaryNaNPropagationMode) -> 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.
