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

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.

Member Typedef Documentation

◆ result_type

typedef bool std::bernoulli_distribution::result_type

The type of the range of the distribution.

Definition at line 3519 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 3555 of file random.h.

◆ bernoulli_distribution() [2/2]

std::bernoulli_distribution::bernoulli_distribution ( double  __p)
inlineexplicit

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 3564 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.

Definition at line 3614 of file random.h.

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

◆ min()

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

Returns the greatest lower bound value of the distribution.

Definition at line 3607 of file random.h.

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

◆ operator()()

template<typename _UniformRandomNumberGenerator >

◆ param() [2/2]

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

Sets the parameter set of the distribution.

Parameters
__paramThe new parameter set of the distribution.

Definition at line 3600 of file random.h.

◆ reset()

void std::bernoulli_distribution::reset ( )
inline

Resets the distribution state.

Does nothing for a Bernoulli distribution.
