Hi,

I define arrangement:

typedef CGAL::Cartesian<CGAL::Exact_rational>                   Kernel;

typedef Kernel::Circle_2                                        Circle_2;

typedef CGAL::Arr_circle_segment_traits_2<Kernel>               Traits_2;
typedef CGAL::Arrangement_with_history_2<Traits_2>              Arr_with_hist_2;

and I want to get a vertex position and use it for creation new circle in the arrangement but I should use a Point with rational type as circle position while the type of vertex position is 
Sqrt_extension and CGAL do not convert Sqrt_extension to Rational. Now I do not know how to convert Sqrt_extension to Rational such that do not loss data.(convert exactly)
