class std::lognormal_distribution< _RealType >

A lognormal_distribution random number distribution.

The formula for the normal probability mass function is

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

Inserts a lognormal_distribution random number distribution __x into the output stream __os.

Parameters

__os	An output stream.
__x	A lognormal_distribution random number distribution.

Returns

The output stream with the state of __x inserted or in an error state.

◆ operator==

template<typename _RealType = double>

◆ operator>>

template<typename _RealType = double>

template<typename _RealType1 , typename _CharT , typename _Traits >

Extracts a lognormal_distribution random number distribution __x from the input stream __is.

Parameters

__is	An input stream.
__x	A lognormal_distribution random number generator engine.

Returns

The input stream with __x extracted or in an error state.
