## ◆ compare_squared_radius()

template<typename Kernel >
 Comparison_result CGAL::compare_squared_radius ( const CGAL::Point_3< Kernel > & p, const typename Kernel::FT & sr )

#include <CGAL/Kernel/global_functions.h>

compares the squared radius of the sphere of radius 0 centered at p to sr.

This returns the opposite sign of sr.
