Message-ID: <0d55b31ff4d062f23238f5d618d42115@proxima.alt.za> (raw)

The following code from mpg123/layer3.c (around line 180, as provided
by anyrhine) could not be more intentionally broken:

    double r;
    if (i < 6) {
        double t = tan( (double) i * M_PI / 12.0 );
        r = t / (1.0 + t);
    } else
        r = 1.0;

    tan1_1[i] = r;
    tan2_1[i] = 1.0 - r;
    tan1_2[i] = M_SQRT2 * r;
    tan2_2[i] = M_SQRT2 / (1.0 - r);

Does anyone know how to intelligently stop the division by zero in
line 181?
