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.

Constructor & Destructor Documentation

std::bernoulli_distribution::bernoulli_distribution ( double  __p = 0.5  )  [inline, explicit]

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] $.
