   Friends
       bool operator== (const geometric_distribution &__d1, const geometric_distribution &__d2)
           Return true if two geometric distributions have the same parameters.

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.
