Struct rand::distributions::StandardNormal

pub struct StandardNormal;

Deprecated since 0.7.0:

moved to rand_distr crate

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.
