CGAL users discussion list

I am new to the CGAL environment, and had the luck to start right away with 
the rather new Circular_Kernel, as I need Intersections of Arcs;

To come to the problem: the intersection of arcs has as results points with 
coordinates of the Root_of_2 type; how is it now possible to lay a simple 
line_2 through two of such points, respectively how can I convert Root_of_2 
to any type which can be used in the linear kernel, without loss of accuracy;

when I came to the conclusion that the conversion to double is the only 
possible way (d'oh), i was confronted by another, even more crucial problem:

Is it in any way possible, to get the intersection point(s) of a line_2 with 
a circluar_arc_2 yet? It is possible to cut a line_arc with a circular_arc, 
so why not a line?

Waiting desperately for an answer,
