Detailed Description
template<typename _RealType = double>
class std::lognormal_distribution< _RealType >
A lognormal_distribution random number distribution.
The formula for the normal probability mass function is
![\[ p(x|m,s) = \frac{1}{sx\sqrt{2\pi}} \exp{-\frac{(\ln{x} - m)^2}{2s^2}} \]](form_7.png)
