Rounding Numbers Calculator Formula
To round a number to a certain place value, follow these steps:
1. Look at the digit to the right of the desired place value.
2. If the digit is 5 or greater, add 1 to the digit in the desired place value and replace all digits to the right with zeros.
3. If the digit is less than 5, leave the digit in the desired place value as it is and replace all digits to the right with zeros.
4. If the digit to the right of the desired place value is 5, and there are no digits to the right of it or they are all zeros, then round the digit in the desired place value up if it’s odd, and leave it as it is if it’s even.
For Example:
- To round 3.78 to the nearest tenth, we look at the digit in the hundredth place (8), since it’s greater than or equal to 5, we add 1 to the digit in the tenth place, resulting in 3.8.
- To round 4.132 to the nearest hundredth, we look at the digit in the thousandth place (2), since it’s less than 5, we leave the digit in the hundredth place as it is, resulting in 4.13.
- To round 7.865 to the nearest integer, we look at the digit in the tenth place (6). Since it’s 5 and there are zeros to the right, we round up because 8 is odd, resulting in 8.
This formula helps in rounding numbers to different place values based on specific rules, making calculations easier and more manageable.
