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 3240 of file random.h.

Member Typedef Documentation

typedef bool std::bernoulli_distribution::result_typeThe type of the range of the distribution.

Definition at line 3244 of file random.h.

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 $[0, 1]$.

Definition at line 3277 of file random.h.

Member Function Documentation

result_type std::bernoulli_distribution::max () const [inline]

Returns the least upper bound value of the distribution.

Definition at line 3327 of file random.h.

result_type std::bernoulli_distribution::min () const [inline]

Returns the greatest lower bound value of the distribution.

Definition at line 3320 of file random.h.

template<typename _UniformRandomNumberGenerator > result_type std::bernoulli_distribution::operator() (_UniformRandomNumberGenerator & __urng) [inline]

Generating functions.

double std::bernoulli_distribution::p () const [inline]

Returns the p parameter of the distribution.

Definition at line 3298 of file random.h.

void std::bernoulli_distribution::param (const param_type & __param) [inline]

Sets the parameter set of the distribution. Parameters:

__param The new parameter set of the distribution.

param_type std::bernoulli_distribution::param () const [inline]

Returns the parameter set of the distribution.

Definition at line 3305 of file random.h.

void std::bernoulli_distribution::reset () [inline]

Resets the distribution state. Does nothing for a Bernoulli distribution.
