.SS "template<typename _IntType = int, typename _RealType = double>class std::geometric_distribution< _IntType, _RealType >"
A discrete geometric random number distribution\&. 

The formula for the geometric probability mass function is $ p(i) = (1 - p)p^{i-1} $ where $ p $ is the parameter of the distribution\&.
