Struct FiniteF64

pub struct FiniteF64(/* private fields */);

A finite 64-bit floating point type.

This is a restricted version of f64 that does not allow NaN or infinity.

Implementations

impl FiniteF64

pub const MAX: Self

Largest finite value.

pub const MIN: Self

Smallest finite value.

pub const EPSILON: Self

Smallest positive normal value.
