Excuse me, may I clarify something about the following function in CGAL?


FT squared_radius ( Point_2<Kernel> p, Point_2<Kernel> q, Point_2<Kernel> r)
compute the squared radius of the circle passing through the points $$p, $$q, and $$r.
Precondition: $$p, $$q, and $$r are not collinear.

The documentation mention the term "squared radius"

If the radius of the circle passing through p, q and r equal to R
then, is it that the above function return R * R but not R?

Thank you very much
