\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}.
