Rounding means making a number simplerbut keeping its value close to what it was. The result is less accurate, but easier to use.
There are several different methods for rounding. Here we look at the common method, the one used by most people. First some examples (explanations follow):
Decide which is the last digit to keepLeave it the same if the next digit is less than 5 (this is called rounding down)But increase it by 1 if the next digit is 5 or more (this is called rounding up)5 is in the middle ... so we couldgo up or down. But we need a method that everyone agrees to. Think about sport: we should have the same number of players on each team, right? And that is the "common" method of rounding. Read about other methods of rounding. A farmer counted 87 cows in the field, but when he rounded them up he had 90.
First work out which number will be left when we finish. 1. Rounding to tenths means to leave one numberafter the decimal point. 2. Rounding to hundredths means to leave two numbersafter the decimal point. 3. etc. To round to "so many decimal places" count that many digits from the decimal point:
To round to "so many" significant digits, count digits from left to right, and then round off from there. When there are leading zeros (such as 0.006), don't count them because they are only there to show how small the number is:
(Try increasing or decreasing the number of significant digits. Also try numbers with lots of zeros in front of them like 0.00314, 0.0000314 etc)
