## Functions
template<typename Kernel >
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.
template<typename Kernel >
Comparison_result | CGAL::compare_signed_distance_to_line (const CGAL::Point_2< Kernel > &p, const CGAL::Point_2< Kernel > &q, const CGAL::Point_2< Kernel > &r, const CGAL::Point_2< Kernel > &s)
| returns `CGAL::LARGER` iff the signed distance of `r` and `l` is larger than the signed distance of `s` and `l`, `CGAL::SMALLER`, iff it is smaller, and `CGAL::EQUAL` iff both are equal, where `l` is the directed line through `p` and `q`.
