CGAL::compare_signed_distance_to_line

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

Comparison_result
compare_signed_distance_to_line ( Point_2<Kernel> p,
Point_2<Kernel> q,
Point_2<Kernel> r,
Point_2<Kernel> s)
returns LARGER iff the signed distance of r and l is larger than the signed distance of s and l, SMALLER, iff it is smaller, and EQUAL iff both are equal, where l is the directed line through p and q.
