pub struct PositiveF32(/* private fields */);
Expand description

An immutable, finite f32 that is known to be >= 0.

Implementations§

source§

impl PositiveF32

source

pub const ZERO: Self = _

A PositiveF32 value initialized with zero.

source

pub fn new(n: f32) -> Option<Self>

Creates a new PositiveF32 if the given value is >= 0.

Returns None for negative, NaN and infinity.

source

pub const unsafe fn new_unchecked(n: f32) -> Self

Creates a new PositiveF32 without checking the value.

Safety

n must be finite and >= 0.

source

pub const fn get(&self) -> f32

Returns the value as a primitive type.

source

pub const fn get_finite(&self) -> FiniteF32

Returns the value as a FiniteF32.

Trait Implementations§

impl ApproxEq for PositiveF32

§

type Margin = F32Margin

This type type defines a margin within which two values are to be considered approximately equal. It must implement Default so that approx_eq() can be called on unknown types.
source§

fn approx_eq<M: Into<Self::Margin>>(self, other: Self, margin: M) -> bool

This method tests that the self and other values are equal within margin of each other.
source§

fn approx_ne<M>(self, other: Self, margin: M) -> bool
where M: Into<Self::Margin>,

This method tests that the self and other values are not within margin of each other.
source§

impl ApproxEqUlps for PositiveF32

§

type Flt = f32

source§

fn approx_eq_ulps(&self, other: &Self, ulps: i32) -> bool

This method tests for self and other values to be approximately equal within ULPs (Units of Least Precision) floating point representations. Differing signs are always unequal with this method, and zeroes are only equal to zeroes. Use approx_eq() from the ApproxEq trait if that is more appropriate.
source§

fn approx_ne_ulps(&self, other: &Self, ulps: <Self::Flt as Ulps>::U) -> bool

This method tests for self and other values to be not approximately equal within ULPs (Units of Least Precision) floating point representations. Differing signs are always unequal with this method, and zeroes are only equal to zeroes. Use approx_eq() from the ApproxEq trait if that is more appropriate.
