Initial Comment:
exp~ just copies it's input to it's output.  this is because exp_tilde_perform in d_math.c does this:

t_int *exp_tilde_perform(t_int *w)
{
    t_sample *in1 = (t_sample *)(w[1]);
    t_sample *out = (t_sample *)(w[2]);
    int n = (int)(w[3]);
    while (n--)
        *out = exp(*in1);
        // out and in1 are never incremented
    return (w+4);
}

instead it should do this:

t_int *exp_tilde_perform(t_int *w)
{
    t_sample *in1 = (t_sample *)(w[1]);
    t_sample *out = (t_sample *)(w[2]);
    int n = (int)(w[3]);
    while (n--)
    {
        *out = exp(*in1);
        out++;
        in1++;
    }
    return (w+4);
}

please apply the attached patch to d_math.c
