Well, having laid quite a few floors, the limits of significance rears its ugly head with ceramic tiles as well. If you think you can measure a ceramic tile to better than 4 binary significant digits in inches, you are kidding yourself. And If you think you can cut it closer than 4 significant digits, seek help: you’ve got delusions of grandeur. (4 significant binary digits of inches is sixteenths of an inch.)

Oh, I concur, and I have already applauded your point on accuracy and precision in physical measurement in a previous post.

But I still maintain that, depending on the value/merit of what is being measured, significant digit limitations can be costly and impractical.
