Required Associated Constants§

Provided Associated Constants§

source

const DIV_EPSILON: Self = Self::EPSILON

Required Methods§

source

fn value(v: f32) -> Self

Provided Methods§

source

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.
