Hi,
I just sent a mail I didn't mean to send, I said:

I questioned this, but I think it's pretty fine, obviously; I meant to
ask about:
> (scm_difference): (- 0 0.0) now returns -0.0. Previously it returned
> 0.0. Also make sure that (- 0 0.0+0.0i) will return -0.0-0.0i.
Is this right? I can convince myself both ways.
Regards,
Andy
