So I could be wrong!) If I ever need more precision than this I will just look it up. ;-D I doubt that I ever will, since this is more than accurate enough to navigate to the moon should I ever build a Pic controlled spacecraft. Thanks everyone! It's been fun. I love a good argument. I'm still not convinced though. TTYL -- http://www.piclist.com#nomail Going offline?
