What version of AutoCAD are you using?

What are you building that you need that level of precision in your dimensions?

Are your coordinates large, such as over 1,000,000?
AutoCAD is notoriosly lousy at accurate calculations when objects have large coordinate values.

Yeah,
I had this issue in the past too.
After I move it as close as possible to 0,0.. the problem solved.
