No it won't distinguish between +0.0 and -0.0 in its present form,
because these two have the same value according to the C equality
operator.  This should be easy to adjust, eg we could exclude -0.0 by
changing the comparison
    if (fval == 0.0)
into 
    static double positive_zero = 0.0;
    ...
    if (!memcmp(&fval, &positive_zero, sizeof(double)))
