The type of the range of the distribution.

template<typename _RealType = double> result_type std::lognormal_distribution< _RealType >::max () const [inline]

Returns the least upper bound value of the distribution.

template<typename _RealType = double> result_type std::lognormal_distribution< _RealType >::min () const [inline]

Returns the greatest lower bound value of the distribution.

Generating functions.

Referenced by operator()().

template<typename _RealType = double> param_type std::lognormal_distribution< _RealType >::param () const [inline]

Returns the parameter set of the distribution.

template<typename _RealType = double> void std::lognormal_distribution< _RealType >::param (const param_type & __param) [inline]

Sets the parameter set of the distribution.

Parameters

__param The new parameter set of the distribution.

template<typename _RealType = double> void std::lognormal_distribution< _RealType >::reset () [inline]

Resets the distribution state.

template<typename _RealType = double> template<typename _RealType1, typename _CharT, typename _Traits> std::basic_ostream< _CharT, _Traits > & operator<< (std::basic_ostream< _CharT, _Traits > & __os, const std::lognormal_distribution< _RealType1 > & __x) [friend]

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.

Return true if two lognormal distributions have the same parameters and the sequences that would be generated are equal.

template<typename _RealType = double> template<typename _RealType1, typename _CharT, typename _Traits> std::basic_istream< _CharT, _Traits > & operator>> (std::basic_istream< _CharT, _Traits > & __is, std::lognormal_distribution< _RealType1 > & __x) [friend]

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.
