## CGAL::compare_y

Comparison_result | compare_y ( Point_2<Kernel> p, Point_2<Kernel> q)
|  | compares Cartesian y-coordinates of p and q.
Comparison_result | compare_y ( Point_3<Kernel> p, Point_3<Kernel> q)
|  | compares Cartesian y-coordinates of p and q.

Comparison_result

compare_y ( | Point_2<Kernel> p, Line_2<Kernel> l1, Line_2<Kernel> l2)

|  | compares the y-coordinates of p and the intersection of lines l1 and l2, see (a) in the figure above.

Comparison_result
