Enum NonfiniteBehavior 

pub enum NonfiniteBehavior {
    IEEE754,
    NanOnly,
}

How the nonfinite values Inf and NaN are represented.

Variants

IEEE754

Represents standard IEEE 754 behavior. A value is nonfinite if the exponent field is all 1s. In such cases, a value is Inf if the significand bits are all zero, and NaN otherwise

NanOnly

Only the Float8E5M2 has this behavior. There is no Inf representation. A value is NaN if the exponent field and the mantissa field are all 1s. This behavior matches the FP8 E4M3 type described in https://arxiv.org/abs/2209.05433. We treat both signed and unsigned NaNs as non-signalling, although the paper does not state whether the NaN values are signalling or not.

Trait Implementations

impl Clone for NonfiniteBehavior

fn clone(&self) -> NonfiniteBehavior

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl PartialEq for NonfiniteBehavior

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