bool operator== (const bernoulli_distribution &__d1, const bernoulli_distribution &__d2)
Return true if two Bernoulli distributions have the same parameters.

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.

typedef bool std::bernoulli_distribution::result_type

The type of the range of the distribution.

Constructs a Bernoulli distribution with likelihood 0.5.

Constructs a Bernoulli distribution with likelihood p.

Parameters

__p [IN] The likelihood of a true result being returned. Must be in the interval $[0, 1]$.

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

Returns the least upper bound value of the distribution.

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

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

Returns the greatest lower bound value of the distribution.

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

Generating functions.

References operator()().

Referenced by operator()().

Returns the p parameter of the distribution.

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

Returns the parameter set of the distribution.

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.

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

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

Return true if two Bernoulli distributions have the same parameters.
