Description (last modified by )
one can get non-NULL zero elements:
- for coeffs
- while applying a function
1.sing 3. ring r1 = (0,a),x,dp;
1.sing 4>
1.sing 5. number c = (a3+2); poly m = c*x; ideal I = m;
1.sing 6>
1.sing 7. ring r2 = (0,a),x,dp; minpoly = a3+2; map f = r1,x;
1.sing 8>
1.sing 9. imap(r1, c); _ == 0; // wrong result (!= 0)!
(a3+2)

1.sing 10> fetch(r1, c); _ == 0; // wrong result (!= 0)!
