Detailed Description¶

template<typename _IntType = int>class std::geometric_distribution< _IntType >¶

A discrete geometric random number distribution. The formula for the geometric probability density function is $p(i|p) = p(1 - p)^{i}$ where $p$ is the parameter of the distribution. Definition at line 3603 of file random.h.

Member Typedef Documentation¶

template<typename _IntType = int> typedef _IntType std::geometric_distribution< _IntType >:: result_type¶

The type of the range of the distribution. Definition at line 3606 of file random.h.

Member Function Documentation¶

template<typename _IntType = int> result_type std::geometric_distribution< _IntType >::max () const [inline]¶

Returns the least upper bound value of the distribution. Definition at line 3695 of file random.h. References std::numeric_limits< _Tp >::max().

template<typename _IntType = int> result_type std::geometric_distribution< _IntType >::min () const [inline]¶

Returns the greatest lower bound value of the distribution. Definition at line 3688 of file random.h.

template<typename _IntType = int> template<typename _UniformRandomNumberGenerator > result_type std::geometric_distribution< _IntType >::operator() (_UniformRandomNumberGenerator &__urng) [inline]¶

Generating functions. Definition at line 3703 of file random.h. References std::geometric_distribution< _IntType >::operator()(), and std::geometric_distribution< _IntType >::param(). Referenced by std::geometric_distribution< _IntType >::operator()().

template<typename _IntType = int> double std::geometric_distribution< _IntType >::p () const [inline]¶

Returns the distribution parameter p. Definition at line 3666 of file random.h.

template<typename _IntType = int> param_type std::geometric_distribution< _IntType >::param () const [inline]¶

Returns the parameter set of the distribution. Definition at line 3673 of file random.h. Referenced by std::geometric_distribution< _IntType >::operator()(), std::operator==(), and std::operator>>().

template<typename _IntType = int> void std::geometric_distribution< _IntType >::param (const param_type &__param) [inline]¶

Sets the parameter set of the distribution. Parameters: Definition at line 3681 of file random.h.

template<typename _IntType = int> void std::geometric_distribution< _IntType >::reset () [inline]¶

Resets the distribution state. Does nothing for the geometric distribution. Definition at line 3660 of file random.h.
