CGAL 5.4 - Polynomial
PolynomialTraits_d::SignAt Concept Reference

Definition

This AdaptableFunctor returns the sign of a PolynomialTraits_d::Polynomial_d \( p\) at given Cartesian point represented as an iterator range.

This functor is well defined if PolynomialTraits_d::Innermost_coefficient_type is RealEmbeddable.

◆ operator()()

template<class InputIterator >
result_type PolynomialTraits_d::SignAt::operator() ( PolynomialTraits_d::Polynomial_d  p,
InputIterator  begin,
InputIterator  end 
)

Returns the sign of \( p\) at the given Cartesian point, where begin is referring to the innermost variable.

Precondition
(end-begin == PolynomialTraits_d::d)
std::iterator_traits< InputIterator >::value_type is ExplicitInteroperable with PolynomialTraits_d::Innermost_coefficient_type.
