Comparison_result  CGAL::compare_signed_distance_to_line (const CGAL::Line_2< Kernel > &l, const CGAL::Point_2< Kernel > &p, const CGAL::Point_2< Kernel > &q) 
 returns CGAL::LARGER iff the signed distance of p and l is larger than the signed distance of q and l , CGAL::SMALLER , iff it is smaller, and CGAL::EQUAL iff both are equal.
