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

Returns the least upper bound value of the distribution.

Definition at line 2971 of file random.h.

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

Returns the greatest lower bound value of the distribution.

Definition at line 2964 of file random.h.

template<typename _RealType = double> template<typename _UniformRandomNumberGenerator > result_type std::fisher_f_distribution< _RealType >::operator() (_UniformRandomNumberGenerator & __urng) [inline]

Generating functions.

Definition at line 2979 of file random.h.

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

Sets the parameter set of the distribution. Parameters:

__param The new parameter set of the distribution.

Definition at line 2957 of file random.h.

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

Returns the parameter set of the distribution.

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

Inserts a fisher_f_distribution random number distribution __x into the output stream __os. Parameters:

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

Returns:

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

template<typename _RealType = double> template<typename _RealType1 > bool operator== (const std::fisher_f_distribution< _RealType1 > & __d1, const std::fisher_f_distribution< _RealType1 > & __d2) [friend]

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

Definition at line 3000 of file random.h.

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

Extracts a fisher_f_distribution random number distribution __x from the input stream __is. Parameters:

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

Returns:

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