Comparison_result  CGAL::compare_signed_distance_to_plane (const CGAL::Plane_3< Kernel > &h, const CGAL::Point_3< Kernel > &p, const CGAL::Point_3< Kernel > &q) 
 returns CGAL::LARGER iff the signed distance of p and h is larger than the signed distance of q and h , CGAL::SMALLER , iff it is smaller, and CGAL::EQUAL iff both are equal.
