D.2.4.7 maxcoef

Procedure from library poly.lib (see poly_lib).

Usage:

maxcoef(f); f poly/ideal/vector/module/matrix

Return:

maximal length of coefficient of f of type int (by counting the length of the string of each coefficient)

Example:

LIB "poly.lib";
ring r= 0,(x,y,z),ds;
poly g = 345x2-1234567890y+7/4z;
maxcoef(g);
→ 10
ideal i = g,10/1234567890;
maxcoef(i);
→ 11
// since i[2]=1/123456789
