The Fisher F distribution is a real valued distribution with two parameters m and n.
It has .

construct/copy/destruct(RealType m = , RealType n = );
Constructs a

fisher_f_distribution
public member functionstemplate<typename URNG> RealType (URNG & urng);
Returns a random variate distributed according to the F distribution.
template<typename URNG> RealType (URNG & urng, const param_type & param) ;
Returns a random variate distributed according to the F distribution with parameters specified by param
.
RealType () ;
Returns the "m" parameter of the distribution.
RealType () ;
Returns the "n" parameter of the distribution.
RealType () ;
Returns the smallest value that the distribution can produce.
RealType () ;
Returns the largest value that the distribution can produce.
param_type () ;
Returns the parameters of the distribution.
void (const param_type & param);
Sets the parameters of the distribution.
void ();
Effects: Subsequent uses of the distribution do not depend on values produced by any engine prior to invoking reset.
