Learn how to use the round function in Notion formulas.

The round() function rounds its argument to the nearest integer (whole number).

round(number) number.(round)

The exact midpoint between two whole numbers will round up towards positive infinity, not “away from zero”.

For example: round(-4.5) will round up to 4.

Rounding Functions - ceil, floor, round, trunc
Note: Notion formulas don’t have a trunc() function (this graphic shows JavaScript rounding functions). But you can build your own trunc expression – see the bottom of this section in the ceil() article.
round(4.5) /* Output: 5 */ 4.49.round() /* Output: 4 */ round(-4.49) /* Output: -4 */ -4.5.round() /* Output: -4 */ round(-4.51) /* Output: -5 */

The round() function doesn’t accept additional arguments, so it can’t natively round a number to a specific decimal place.

However, you can accomplish this using the following formula:

/* Round to two decimal places */ round([number] * 100) / 100 /* Round to three decimal places */ round([number] * 1000) / 1000

The number of zeroes corresponds to the number of decimal places to which your number will be rounded.

round(9.24551 * 10) / 10 /* Output: 9.2 */ (4.158015 * 100).round() / 100 /* Output: 4.16 */ round(5145.018394 * 10000) / 10000 /* Output: 5145.0184 */

The example database below contains a formula that rounds the input number to several different decimal places.

"One Decimal: " + (round(prop("Number") * 10) / 10) + "\nTwo Decimals: " + (round(prop("Number") * 100) / 100) + "\nThree Decimals: " + (round(prop("Number") * 1000) / 1000) + "\nFour Decimals: " + (round(prop("Number") * 10000) / 10000) + "\nFive Decimals: " + (round(prop("Number") * 100000) / 100000)

This formula demonstrates decimal-rounding to five different places.

Each rounded number is then converted to a string using the format function, allowing us to craft a five-line block of text.

Note how \n allows us to create a new line in the formula output.
