Polynomials over the Integers

The functions in this section are available for multivariate polynomials over the integers only.

Sign(f): RngMPolElt -> RngIntElt

The sign of the leading coefficient of \(f\).

AbsoluteValue(f): RngMPolElt -> RngMPolElt

Abs(f): RngMPolElt -> RngMPolElt

Return either \(f\) or \(-f\) according to which one has non-negative leading coefficient.

MaxNorm(f): RngMPolElt -> RngIntElt

The maximum of the absolute values of the coefficients of \(f\).

SumNorm(f): RngMPolElt -> RngIntElt

The sum of the base coefficients of \(f\).
