Detailed Description

template<class RealType = double>
class boost::random::normal_distribution_v156< RealType >

Instantiations of class template normal_distribution_v156 model a . Such a distribution produces random numbers x distributed with probability density function $\displaystyle p(x) = \frac{1}{\sqrt{2\pi}\sigma} e^{-\frac{(x-\mu)^2}{2\sigma^2}} $, where mean and sigma are the parameters of the distribution.
