AlgebraicKernelForSpheres::SignAt

Definition

A model fo of this concept must provide:

CGAL::Sign
fo ( AlgebraicKernelForSpheres::Polynomial_1_3 p ,
AlgebraicKernelForSpheres::Root_for_spheres_2_3 r )
Computes the sign of polynomial p evaluated at a root r.

CGAL::Sign
fo ( AlgebraicKernelForSpheres::Polynomial_for_spheres_2_3 p ,
AlgebraicKernelForSpheres::Root_for_spheres_2_3 r )
Same as previous.
