CGAL 4.12 - Polynomial
PolynomialTraits_d::Shift Concept Reference

## Definition

This AdaptableBinaryFunction multiplies a PolynomialTraits_d::Polynomial_d by the given power of the specified variable.

This functor is provided for efficiency reasons, since multiplication by some variable will in general correspond to a shift of coefficients in the internal representation.
