## CGAL::operator-

Vector_2<Kernel> | operator- ( Point_2<Kernel> p, Point_2<Kernel> q)
|  | returns the difference vector between q and p. You can substitute ORIGIN for either p or q ,but not for both.
Point_2<Kernel> | operator- ( Point_2<Kernel> p, Vector_2<Kernel> v)
|  | returns the point obtained by translating p by the vector -v.
Vector_3<Kernel> | operator- ( Point_3<Kernel> p, Point_3<Kernel> q)
|  | returns the difference vector between q and p. You can substitute ORIGIN for either p or q, but not both.
Point_3<Kernel> | operator- ( Point_3<Kernel> p, Vector_3<Kernel> v)
|  | returns a point obtained by translating p by the vector -v.
