Struct rand::distributions::exponential::Exp1

pub struct Exp1(pub f64);

Unstable (rand)

: use rand from crates.io

A wrapper around an f64 to generate Exp(1) random numbers.

See Exp for the general exponential distribution. Note 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. The exact description in the paper was adjusted to use tables for the exponential distribution rather than normal.
