Rounding
Ordinarily, the process of rounding numbers is used to reduce their precision. The digit to the right of the place being rounded to is examined. If it is 5 or more, then the digit in the place being rounded to is increased by 1. All digits to the right of the place being rounded to are dropped.
Example
9.995 rounds to 10.00 when rounded to the hundredths place.
9.994 rounds to 9.99 when rounded to the hundredths place.
