Detailed Description

   template<typename _RealType = double>
       class std::normal_distribution< _RealType >" A normal continuous distribution for random numbers.

       The formula for the normal probability density function is p(x|,ma) = ac{1}{ma t{2 i}}
       e^{- ac{{x - }^ {2}}{2 ma ^ {2}} } ]
