pub struct OpenClosed01;
Expand description

A distribution to sample floating point numbers uniformly in the half-open interval (0, 1], i.e. including 1 but not 0.

All values that can be generated are of the form n * ε/2. For f32 the 24 most significant random bits of a u32 are used and for f64 the 53 most significant bits of a u64 are used. The conversion uses the multiplicative method.

See also: Standard which samples from [0, 1), Open01 which samples from (0, 1) and Uniform which samples from arbitrary ranges.

§Example

use rand::{thread_rng, Rng};
use rand::distributions::OpenClosed01;

let val: f32 = thread_rng().sample(OpenClosed01);
println!("f32 from (0, 1): {}", val);
