template<class InputIterator >
result_type PolynomialTraits_d::IsZeroAt::operator() ( PolynomialTraits_d::Polynomial_d  p,
InputIterator  begin,
InputIterator  end 
)

Computes whether \( p\) is zero at the Cartesian point given by the iterator range, 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.
