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.
