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.

Member Typedef Documentation
template<typename _IntType = int> typedef _IntType std::geometric_distribution< _IntType >::result_type
The type of the range of the distribution.
