Struct rand::distributions::exponential::Exp1

pub struct Exp1(pub f64);

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

See Exp for the general exponential distribution.

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.
