In my program,I included these following head files:
 

#include <CGAL/Exact_predicates_exact_constructions_kernel.h>
#include <CGAL/Delaunay_triangulation_3.h>
 
and my type definition:
 
typedef CGAL::Exact_predicates_exact_constructions_kernel  K;
typedef CGAL::Delaunay_triangulation_3<K>                  Delaunay;
typedef Delaunay::Point                                    Point;
 
I find I can not assign the coordinate of one point that is Point type to variable of double type,like this:
   
 double x=p.x();
 
why ?and how can assign p.x() to x?
 
any help will be appreciated,thank you.
