CGAL 5.5.1 - Polynomial
PolynomialTraits_d::Negate Concept Reference

## Definition

This AdaptableUnaryFunction computes $$p(-x)$$ for a given polynomial $$p$$.

Note that this functor operates on the polynomial in the univariate view, that is, the polynomial is considered as a univariate polynomial in one specific variable.

This functor is provided for efficiency reasons, since this operation just flips the sign of all odd coefficients with respect to the specified variable.

## ◆ operator()()

 result_type PolynomialTraits_d::Negate::operator() ( argument_type p, int i )

Returns $$p(-x)$$, with respect to variable $$x_i$$.

Precondition
$$0 \leq i < d$$.
