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.

pub const ZERO: Self

Zero.

pub const unsafe fn new_unchecked(value: f64) -> Self

Creates a finite float without checking whether the value is finite. This results in undefined behavior if the value is non-finite.

Safety

The value must not be NaN or infinite.

pub fn new(value: f64) -> Option<Self>

Creates a finite float if the value is finite.

pub fn cast_from_u64(value: u64) -> Self

Creates a FiniteF64 from a u64 by casting the value to a float.

The cast is guaranteed to be finite but may not be accurate.

pub const fn to_f64(self) -> f64
