Struct rand::distributions::normal::StandardNormal

pub struct StandardNormal(pub f64);

A wrapper around an f64 to generate N(0, 1) random numbers (a.k.a. a standard normal, or Gaussian).

See Normal for the general normal distribution.

Implemented via the ZIGNOR variant[1] of the Ziggurat method.
