Ah, thanks. I also forgot to ask the other part of the question, though this
helps me get to the point:
I want to convert values in my Point_3 to doubles (for rendering, output,
etc.), but when I write

p.x().exact().to_double()

or

p.x().to_double() I get the error:

Better use CGAL::to_double instead of hoping for a member function.


Is FT not Lazy_exact_nt< CGAL::Gmpq >?

Apparently not, seems to be some undocumented polynomial type (look at CGAL/Nef_polynomial.h if you need details about that type).
