Struct rand::distributions::normal::Normal

pub struct Normal {
    // some fields omitted
}

Unstable (rand)

: use rand from crates.io

The normal distribution N(mean, std_dev**2).

This uses the ZIGNOR variant of the Ziggurat method, see StandardNormal for more details.

Methods

impl Normal

fn new(mean: f64, std_dev: f64) -> Normal

Unstable (rand)

: use rand from crates.io

Construct a new Normal distribution with the given mean and standard deviation.

Panics

Panics if std_dev < 0.
