[][src]Struct rand::distributions::StandardNormal

pub struct StandardNormal;

Samples floating-point numbers according to the normal distribution N(0, 1) (a.k.a. a standard normal, or Gaussian). This is equivalent to Normal::new(0.0, 1.0) but faster.

See Normal for the general normal distribution.

Implemented via the ZIGNOR variant1 of the Ziggurat method.

Example

use rand::prelude::*;
use rand::distributions::StandardNormal;

let val: f64 = SmallRng::from_entropy().sample(StandardNormal);
println!("{}", val);
