Struct std::rand::distributions::exponential::Exp1
[−]
[src]
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.
