6.4.4 Set Operations RC

rc_interval<T> hull(const rc_interval<T>& a, const rc_interval<T>& b); 
rc_interval<T> intersection(const rc_interval<T>& a, const rc_interval<T>& b);

Set operations given two rectangular complex intervals, A,B∈ RC  :

hull(const rc_interval<T>& a, const rc_interval<T>& b)


Returns an interval that contains both A and B .

intersection(const rc_interval<T>& a, const rc_interval<T>& b)


Returns an interval that is the intersection of A and B .
