CGAL 5.5.2  2D and 3D Linear Geometry Kernel

Functions  
template<typename Kernel >  
Comparison_result  CGAL::compare_lexicographically (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. More...  
template<typename Kernel >  
Comparison_result  CGAL::compare_lexicographically (const CGAL::Point_3< Kernel > &p, const CGAL::Point_3< Kernel > &q) 
Compares the Cartesian coordinates of points p and q lexicographically in \( xyz\) order: first \( x\)coordinates are compared, if they are equal, \( y\)coordinates are compared, and if both \( x\) and \( y\) coordinate are equal, \( z\)coordinates are compared. More...  
Comparison_result CGAL::compare_lexicographically  (  const CGAL::Point_2< Kernel > &  p, 
const CGAL::Point_2< Kernel > &  q  
) 
#include <CGAL/Kernel/global_functions.h>
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.
This is the same function as compare_xy
and exists for compatibility with Point_d<Kernel>
.
