The extreme value distribution is a real valued distribution with two parameters a and b.
It has .

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