What is Rounding?
Rounding is the process of adjusting the digits of a number to make it simpler while retaining its value as closely as possible. When rounding to a certain number of decimal places, the following rules typically apply:
- Identify the Decimal Place: Determine which decimal place you need to round to.
- Look at the Next Digit: If the digit immediately after the desired decimal place is 5 or greater, round up. If it is less than 5, round down.
- Adjust the Number: Change the last digit at the desired decimal place according to the rounding rules.

- Example: If you have the number 3.14159265 and want to round it to five decimal places:
- Identify the sixth decimal place (which is 9).
- Since 9 is greater than 5, you round up the fifth decimal place (2) to 3.
- The rounded number is 3.14160.
