Hi,
 I am using convex_hull_3, but it makes a very long time and does not stop computing (with the tutorial of Le-Jeng Shiue, Pierre Alliez, Radu Ursu and Lutz Kettner, http://www.cgal.org/Tutorials/Polyhedron/index.html) , even for 48 vertices, i tried to do with MP_Float, Gmpz, Gmpq with Homogeneous but the problem still exists, can you tell me if Gmpz can store float numbers? and how to convert between the different number_types. I want to know how to convert from a Polyhedron_3 with for example Cartesian<double> or simple_cartesian<double> to Polyhedron_3 with Homogeneous<MP_Float> or Homogeneous<Gmpz>. Finally, i want to know how i can convert from enriched_polyhedron<double> to CGAL::Polyhedron_3<CGAL::MP_Float> in the tutorial.

Thanks in advance
Hichem
