Summary: exp~ broken/fixed
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
