For a Sun Tracking application I am making the, possibly invalid,
assumption
that your numeric range is limited to 0.00 to 359.99.
My solution would be to change the domain space. Treat the calculations as
a monetary calculation and do all of the math in BCD. Issues of rounding
and
non-integer math are removed.
Ron, on gmail your messages keep coming across as "noname" attachments,
might want to check your email client settings.
