Definition

This AdaptableFunctor returns the sign of a PolynomialTraits_d::Polynomial_d $p$ at a given homogeneous point, which is given by an iterator range.

The polynomial is interpreted as a homogeneous polynomial in all variables.

For instance the polynomial $p(x_0,x_1) = x_0^2x_1^3+x_1^4$ is interpreted as the homogeneous polynomial $p(x_0,x_1,w) = x_0^2x_1^3+x_1^4w^1$ .

	)

Returns the sign of $p$ at the given homogeneous point, where begin is referring to the innermost variable.

Precondition: (end-begin==PolynomialTraits_d::d+1); std::iterator_traits< InputIterator >::value_type is ExplicitInteroperable with PolynomialTraits_d::Innermost_coefficient_type.
