Functions
template<typename Kernel >
Comparison_result	CGAL::compare_xy (const CGAL::Point_2< Kernel > &p, const CGAL::Point_2< Kernel > &q)
	Compares the Cartesian coordinates of points `p` and `q` lexicographically in $xy$ order: first $x$ -coordinates are compared, if they are equal, $y$ -coordinates are compared.

template<typename Kernel >
Comparison_result	CGAL::compare_xy (const CGAL::Point_3< Kernel > &p, const CGAL::Point_3< Kernel > &q)
	Compares the Cartesian coordinates of points `p` and `q` lexicographically in $xy$ order: first $x$ -coordinates are compared, if they are equal, $y$ -coordinates are compared.
