CoeffHeight

the maximum of the absolute values of the coefficients of a polynomial

Syntax
CoeffHeight(F: RINGELEM): RINGELEM

Description
This function returns the maximum of the absolute values of the coefficients of F ; naturally, the coefficient ring must be arithmetically ordered.

Example
/**/ use P ::= QQ[x,y];
/**/ f := (2*x-3*y)^2;
/**/ f;
4*x^2 -12*x*y +9*y^2
/**/ CoeffHeight(f);
12
