Hey, I am a nerd. Us nerds rule the world, haven't you heard? Actually, to be more precise, I'm a redneck geek. I can eat squirrel, and solve your homework. Besides "Gone Sledding", what would you rather we talk about, the recite stats of some kid we don't actually know, that runs around with a pig skin, on Sunday?
Now Battlestar Galatica, that's a cool show.

Nothing like mixing religion, high tech, gun fights, and hot robots!

Star wars is your basic high tech good versus evil. Startrek is gay.
To answer your question, due to the precision specified, you definitely could "suppose" an accuracy. But, a digital speedometer is a good example, it might say 46 MPH, but have a accuracy of +/- 5 MPH, or worse. They only build it to be as accurate as the law allows. Plus it'd be stupid if it ticked up in 5 MPH increments. Plus, it would loose additional accuracy.
