## Definition

## Operations
A model of this concept must provide:
CGAL::Sign | operator() (const AlgebraicKernelForSpheres::Polynomial_1_3 &p, const AlgebraicKernelForSpheres::Root_for_spheres_2_3 &r)
| Computes the sign of polynomial `p` evaluated at a root `r`.
CGAL::Sign | operator() (const AlgebraicKernelForSpheres::Polynomial_for_spheres_2_3 &p, const AlgebraicKernelForSpheres::Root_for_spheres_2_3 &r)
| Same as previous.
