Yeah, lol, you will NEVER, EVER acheive that kind of precision with anything in the real world. As far as CAD goes, just round it and forget it. Even CAD has some sort of tolerance. And to the 7th decimal place is pretty damn finite.

-How did you draw the square, with the "rectangle" command?

-AutoCAD is usually accurate to something like 30 significant figures, so you should not have that error. But if coordinates are very large, such as over 1,000,000 error bebomes noticeable which can affect some operations and precision.
