\begin{ccRefConcept}{PolynomialTraits_d::SignAt}
\ccDefinition
This \ccc{AdaptableFunctor} returns the sign of a
\ccc{PolynomialTraits_d::Polynomial_d} $p$ at given Cartesian point represented
as an iterator range.
This functor is well defined if \ccc{PolynomialTraits_d::Innermost_coefficient_type} is
\ccc{RealEmbeddable}.
