Dear Monique Teillaud,
Could you please tell me where I can find a software in your lib related to straight skeleton generation?
Thanks very much!

Hi Amir
If you only need square roots, you can use CGAL::Root_of_2<RT> or
alternatively the new CGAL::Sqrt_extension<NT,ROOT>
They are robust and quite efficient compared to the more powerful Core
expressions.
Best,
