bool operator== (const bernoulli_distribution &__d1, const bernoulli_distribution &__d2)

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.

typedef bool \fBstd::bernoulli_distribution::result_type\fP

The type of the range of the distribution.

Definition at line 3578 of file random.h.

std::bernoulli_distribution::bernoulli_distribution (double__p = \fC0.5\fP)\fC [inline]\fP, \fC [explicit]\fP

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 3611 of file random.h.

\fBresult_type\fP std::bernoulli_distribution::max () const\fC [inline]\fP

Returns the least upper bound value of the distribution.

Definition at line 3661 of file random.h.

References std::max().

\fBresult_type\fP std::bernoulli_distribution::min () const\fC [inline]\fP

Returns the greatest lower bound value of the distribution.

Definition at line 3654 of file random.h.

References std::min().

template<typename _UniformRandomNumberGenerator > \fBresult_type\fP std::bernoulli_distribution::operator() (_UniformRandomNumberGenerator &__urng)\fC [inline]\fP

Generating functions.

Definition at line 3669 of file random.h.

double std::bernoulli_distribution::p () const\fC [inline]\fP

Returns the p parameter of the distribution.

Definition at line 3632 of file random.h.

\fBparam_type\fP std::bernoulli_distribution::param () const\fC [inline]\fP

Returns the parameter set of the distribution.

void std::bernoulli_distribution::param (const \fBparam_type\fP &__param)\fC [inline]\fP

Sets the parameter set of the distribution.

Parameters:

__param The new parameter set of the distribution.

Definition at line 3647 of file random.h.

void std::bernoulli_distribution::reset ()\fC [inline]\fP

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

Definition at line 3626 of file random.h.

bool operator== (const \fBbernoulli_distribution\fP &__d1, const \fBbernoulli_distribution\fP &__d2)\fC [friend]\fP

Return true if two Bernoulli distributions have the same parameters.
