The purpose of rounding is to make a number easier to work with. The problem is that by rounding you lose some accuracy. To make sure you lose as little accuracy as possible, you should choose the number which is closest to the original (unrounded) one. Take the number 7.1 as an example. To round it to the nearest whole, you'd simply choose 7 because 7 is closer to 7.1 than 8 is.
