Insert the number you’d like to start with, then tap the “round” button.
Using the mode menu, you have the option to change the (normal) round mode to round up or round down, as detailed further below.
Frequently rounded numbers include, for instance:

- Round 9.8 to the Nearest Whole Number
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).
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.
In the table below you can find some numbers rounded to nearest whole number.

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.
