template<typename _IntType = int>class std::binomial_distribution< _IntType >¶
A discrete binomial random number distribution.Member Typedef Documentation¶
template<typename _IntType = int> typedef _IntType std::binomial_distribution< _IntType >:: result_type¶
The type of the range of the distribution. Definition at line 3405 of file random.h.Member Function Documentation¶
template<typename _IntType = int> result_type std::binomial_distribution< _IntType >::max () const [inline]¶
Returns the least upper bound value of the distribution. Definition at line 3512 of file random.h.template<typename _IntType = int> result_type std::binomial_distribution< _IntType >::min () const [inline]¶
Returns the greatest lower bound value of the distribution. Definition at line 3505 of file random.h.template<typename _IntType = int> template<typename _UniformRandomNumberGenerator > result_type std::binomial_distribution< _IntType >::operator() (_UniformRandomNumberGenerator &__urng) [inline]¶
Generating functions. Definition at line 3520 of file random.h. References std::binomial_distribution< _IntType >::operator()(), and std::binomial_distribution< _IntType >::param().

A rejection algorithm when t * p >= 8 and a simple waiting time method - the second in the referenced book - otherwise. NB: The former is available only if _GLIBCXX_USE_C99_MATH_TR1 is defined.

Returns the distribution p parameter. Definition at line 3483 of file random.h.template<typename _IntType = int> param_type std::binomial_distribution< _IntType >::param () const [inline]¶
Returns the parameter set of the distribution. Definition at line 3490 of file random.h. Referenced by std::binomial_distribution< _IntType >::operator()().template<typename _IntType = int> void std::binomial_distribution< _IntType >::param (const param_type &__param) [inline]¶
Sets the parameter set of the distribution. Parameters:__param The new parameter set of the
distribution.
template<typename _IntType = int> void std::binomial_distribution< _IntType >::reset () [inline]¶

Inserts a binomial_distribution random number distribution __x into the output stream __os. Parameters:__os An output stream.
__x A binomial_distribution random number distribution.
Returns:
The output stream with the state of __x
inserted or in an error state.

Extracts a binomial_distribution random number distribution __x from the input stream __is. Parameters:__is An input stream.
__x A binomial_distribution random number generator engine.
Returns:
The input stream with __x extracted or in an
error state.
