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

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

Trait Implementations

impl Clone for TernaryNaNPropagationMode

fn clone(&self) -> TernaryNaNPropagationMode

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for TernaryNaNPropagationMode

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

Formats the value using the given formatter.

impl Default for TernaryNaNPropagationMode

fn default() -> TernaryNaNPropagationMode

Returns the “default value” for a type.

impl From<TernaryNaNPropagationMode> for BinaryNaNPropagationMode
