It's for use in science. It's basically saying that 3 and 2 are both precise to the ones, so when dividing you give an answer that is precise to the ones because if you were to give it to the tenths it would imply a level of precision you do not have. yea but im pretty sure that anything greater than 0.4 would actually get rounded UP, not DOWN...So 1.5 rounded would technically be represented best by a 2, not a 1...
