Guide to Round Decimal Numbers to the Nearest Whole Number
What are the rules to Rounding Decimal Numbers to Whole Numbers?
- It completely relies on the value of the tenth place of the number. The tenth place of a Decimal Number is the number right after the decimal point.
For example, The value of the tenth place of 329.547 is 5.
- If the value of the tenth place of a number is 5 or more (greater than 5), then the value of the place one will be increased by 1.
For example, The value of the place one of 329.547 is 9
If we round 329.547 to a whole number, the value will change to 330.
In the same way, rounding 2453.710 will get you the whole number 2454.
- If the value of the tenth place is 4 or less than 4, then you just need to remove everything after decimal point (including decimal symbol) and remain digits will be the whole number.
For example, If the decimal number is 32.23902, the rounded whole number will be 32. This is because 2 is less than 5
In the same way, rounding 2959.49 will get you whole number 2959.
