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.
