Detailed Description

A Bernoulli random number distribution.

Generates a sequence of true and false values with likelihood that true will come up and that false will appear.

Member Typedef Documentation

typedef bool std::bernoulli_distribution::result_type

The type of the range of the distribution.

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 .
