D.12.1.6 coeffmod

Usage:

coeffmod(f,n);

Assume:

poly f depends on at most var(1) of the basering

Return:

poly f modulo number n

Note:

at first the coefficients of the monomials of the polynomial f are determined, then their remainder modulo n is calculated, after that the polynomial 'is put together' again

LIB "aksaka.lib";
ring R = 0,x,dp;
poly f=2457*x4+52345*x3-98*x2+5;
bigint n=3;
coeffmod(f,n);
==> x3-2x2+2
