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.

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.
