CGAL::compare_squared_radius

Comparison_result compare_squared_radius ( Point_3<Kernel> p, typename Kernel::FT sr)
compares the squared radius of the sphere of radius 0 centered at p to sr. This returns the opposite sign of sr.

Comparison_result compare_squared_radius ( Point_3<Kernel> p, Point_3<Kernel> q, typename Kernel::FT sr)
compares the squared radius of the sphere defined by the points p and q to sr.
