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.

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

The type of the range of the distribution.

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

Returns the least upper bound value of the distribution.

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

Returns the greatest lower bound value of the distribution.

Return true if two geometric distributions have the same parameters.
