Floating point types.

Required Associated Constants

const HALF: Self

0.5

const TWO: Self

2.0

Required Methods

fn from_f64(x: f64) -> Self

Converts from a f64.

fn from_usize(n: usize) -> Self

Converts from a usize.

fn into_usize(self) -> usize

Converts into a usize.

fn u01x2(hash: u64) -> (ClosedOpenUnit<Self>, OpenClosedUnit<Self>)

Generates two uniform random numbers from a random hash value.

The first is sampled from [0.0, 1.0), the second from (0.0, 1.0].

Object Safety

This trait is not object safe.
