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 3972 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 3979 of file random.h.
