Detailed Description

A Bernoulli random number distribution.

Generates a sequence of true and false values with likelihood $p$ that true will come up and $(1 - p)$ that false will appear.

Definition at line 3574 of file random.h.

Member Typedef Documentation

The type of the range of the distribution.

Constructor & Destructor Documentation

std::bernoulli_distribution::bernoulli_distribution ( double  __p = 0.5)
inlineexplicit

Constructs a Bernoulli distribution with likelihood p.

Parameters
__p[IN] The likelihood of a true result being returned. Must be in the interval $[0, 1]$.
