What is the Nearest Whole Number?
The nearest whole number of a decimal number is the value of that number once it has been rounded to the nearest integer (a number without decimals or fractional parts, such as -1,0,1,2, …) depending on the value of the first digit (tenths place which is located one place to the right of the decimal point).
Frequently Asked Questions
- How do you round to the nearest whole number? If the value of the tenths place is less than five, simply remove the decimal point and all decimals. Else, increase the whole number ones place value by 1, then remove the decimal point and the digits to the right of it.
- What does it mean to round to the nearest whole number? It means determining the integer, a number without decimal places or fractional parts, which is closest to the number you start with.
- How do you round a fraction to the nearest whole number? If the nominator of the proper fraction is equal or greater than half the denominator, round up to the nearest integer. Else round down.
- What is 3.5 rounded to the nearest whole number? As the first decimal place value of 3.5 is 5, increase the digit in the whole numbers ones place by 1, and then remove the decimal separator and all digits after the whole number’s place: 3.5 → 4.
- How do you round a decimal to a whole number? Answer: If the first digit after the decimal point is less than 5, round down to the nearest integer. Else round up.
How to Round to the Nearest Whole Number
To round a decimal number to the nearest whole number, check the value of its tenths. If the value is equal to 5 or greater, increase the value in the whole numbers ones place by 1 and then remove the decimal point as well as all digits. If the value is equal to 4 or less, simply remove all the digits and the decimal separator.
For example:
- 3.27: The tenths’ value is 2, so we round down: 3.27 → 3
- 1.9: The tenths’ value is 9, so we round up: 1.9 → 2
- 7 Nothing to be done, the tenths’ value is 0.

Round Up to the Nearest Whole Number
If the digit at the first decimal place of a certain number is >= 5, then, according to general rounding rules, you round up to the nearest whole number. However, the term round up to the nearest whole number means that all first decimal place values in between 1 and 9 are rounded up by adding 1 to the value in the whole numbers ones place, and then removing the decimal point and all digits.
Round Down to the Nearest Whole Number
If the digit at the first decimal place is < 5, then, according to general rounding rules, you round down to the nearest whole number. However, the term round down to the nearest whole number means that first decimal place in between 1 and 9 are rounded down by removing the decimal point and all digits.
Bottom Line
Each and every rounded number has always the same value as the starting number, but its value is less exact.
