## 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.

Definition at line 3523 of file random.h.

## Member Typedef Documentation

## result_type

typedef bool std::bernoulli_distribution::result_type

The type of the range of the distribution.

Definition at line 3527 of file random.h.

## Constructor & Destructor Documentation

## bernoulli_distribution() [1/2]

std::bernoulli_distribution::bernoulli_distribution | ( |  | ) |

inline

Constructs a Bernoulli distribution with likelihood 0.5.

Definition at line 3563 of file random.h.

## bernoulli_distribution() [2/2]

std::bernoulli_distribution::bernoulli_distribution | ( | double | __p | ) |

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 .

Definition at line 3572 of file random.h.

## Member Function Documentation

## max()

result_type std::bernoulli_distribution::max | ( |  | ) | const

inline

Returns the least upper bound value of the distribution.

References std::numeric_limits< _Tp >::max().

## min()

result_type std::bernoulli_distribution::min | ( |  | ) | const

inline

Returns the greatest lower bound value of the distribution.

## operator()()

template<typename _UniformRandomNumberGenerator >

result_type std::bernoulli_distribution::operator() | ( | _UniformRandomNumberGenerator & | __urng | ) |

inline

Generating functions.

Definition at line 3630 of file random.h.

## p()

double std::bernoulli_distribution::p | ( |  | ) | const

inline

Returns the `p` parameter of the distribution.

Definition at line 3593 of file random.h.

## param() [1/2]

param_type std::bernoulli_distribution::param | ( |  | ) | const

inline

Returns the parameter set of the distribution.

## param() [2/2]

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.

Definition at line 3608 of file random.h.

## reset()

void std::bernoulli_distribution::reset | ( |  | ) |

inline

Resets the distribution state.

Does nothing for a Bernoulli distribution.
