Well, in fact not working.

0^0 is domain error (OK)
0^z, z not 0 is (1, 0), but must be (0, 0)
z^0, z not zero is (1, 0), (OK)

Code:

    if (dn_eq0(a) && dn_eq0(b)) {
        if (dn_eq0(c) && dn_eq0(d))
            cmplx_NaN(rx, ry);
        else {
            dn_1(rx);
            decNumberZero(ry);
        }
    } else {
        cmplxLn(&e1, &e2, a, b);
        cmplxMultiply(&f1, &f2, &e1, &e2, c, d);
        cmplxExp(rx, ry, &f1, &f2);
    }

must be:

Code:

    if (dn_eq0(a) && dn_eq0(b)) {
        if (dn_eq0(c) && dn_eq0(d))
            cmplx_NaN(rx, ry);
        else {
            decNumberZero(rx);
            decNumberZero(ry);
        }
    } else {
        cmplxLn(&e1, &e2, a, b);
        cmplxMultiply(&f1, &f2, &e1, &e2, c, d);
        cmplxExp(rx, ry, &f1, &f2);
    }

Regards.
