Detailed Description

   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.
