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 $p(i|p) = (1 - p)p^{i-1}$ where $p$ is the parameter of the distribution.

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.

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 3705 of file random.h.
