## CGAL::compare_xy

Comparison_result | compare_xy ( Point_2<Kernel> p, 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.
Comparison_result | compare_xy ( Point_3<Kernel> p, 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.
