Struct rand::distributions::normal::StandardNormal [-] [+] [src]

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. That this has to be unwrapped before use as an f64 (using either * or mem::transmute is safe).

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