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.

       Since
           C++11
