A model of Polynomial_d is representing a multivariate polynomial in d ≥ 1 variables over some basic ring R. This type is denoted as the innermost coefficient. A model of Polynomial_d accompanied by a traits class CGAL::Polynomial_traits_d<Polynomial_d>, which is a model of PolynomialTraits_d. Please have a look at the concept PolynomialTraits_d, since nearly all functionality related to polynomials is provided by the traits.
The algebraic structure of Polynomial_d depends on the algebraic structure of Innermost_coefficient_type:
Note: In case the polynomial is univariate and the innermost coefficient is a Field the polynomial is model of EuclideanRing.
