PolynomialTraits_d::SignAt

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.

template <class InputIterator>

result_type

fo ( 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)

Precondition:

std::iterator_traits< InputIterator >::value_type is ExplicitInteroperable with PolynomialTraits_d::Innermost_coefficient_type.
