Required Associated Constants

const HALF: Self

const ZERO: Self

const ONE: Self

const TWO: Self

const THREE: Self

const FOUR: Self

const FIVE: Self

const SIX: Self

const SEVEN: Self

const EIGHT: Self

const NINE: Self

const TEN: Self

const MIN: Self

const MAX: Self

const EPSILON: Self

Provided Associated Constants

const DIV_EPSILON: Self = Self::EPSILON

Required Methods

fn value(v: f32) -> Self

Provided Methods

fn epsilon_for(_reference: Self) -> Self

Epsilon constants are usually not a good way to deal with float precision. Float precision depends on the magnitude of the values and so should appropriate epsilons.

Object Safety

This trait is not object safe.
