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

$\‍[ p(x|m,s) = \frac{1}{sx\sqrt{2\pi}} \exp{-\frac{(\ln{x} - m)^2}{2s^2}} \‍]$

Since: C++11
