How to pass double numbers to Surface_mesh_default_criteria_3?

[stla]

Hello,

I want to run this code but with the arguments of criteria given by the user as double numbers. I tried to enclose the double numbers in FT() but that doesn't work:

  CGAL::Surface_mesh_default_criteria_3<Tr> criteria(FT(a),  // angular bound
                                                     FT(b),  // radius bound
                                                     FT(c)); // distance bound

I found:

  FT ab(angle_bound);
  FT rb(radius_bound);
  FT db(distance_bound); 
  CGAL::Surface_mesh_default_criteria_3<Tr> criteria(ab,  // angular bound
                                                     rb,  // radius bound
                                                     db); // distance bound
