Hi all,

Thanks for your comments, but please assume that I DO want to use floating
point operations and not fixed point. There are only two operations that I'm
interested in, addition and integer conversion. Is it possible at all to get
these simple (to me) instructions fast on the AGB?

Regards,

Martijn
