I'm sure this is a really dumb question, but I often see gps coordinates described in the format XX.XX.XX (for example [Only registered and activated users can see links. ]), which confuses me because I can't tell if these are supposed to be DMS format or D.M format. Which are they? If it's supposed to be DMS, then shouldn't it be written XX XX' XX" and if it's D.M format then isn't missing a digit and shouldn't it be XX.XX.XXX?

Thanks in advance to all.
