round
Learn how to use the round function in Notion formulas.
The round() function rounds its argument to the nearest integer (whole number).
1
round(number)
The exact midpoint between two whole numbers will round up towards positive infinity, not โ€œaway from zeroโ€.
For example: round(-4.5) will round up to 4.

1
round(4.5) // Output: 5

3
round(4.49) // Output: 4

5
round(-4.49) // Output: -4
6

7
round(-4.5) // Output: -4
8

round(-4.51) // Output: -5

The round() function doesnโ€™t accept additional arguments, so it canโ€™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
โ€‹
// 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
โ€‹
round(4.158015*100)/100 // Output: 4.16
โ€‹
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: " + format(round(prop("Number") * 10) / 10) +

"\n Two Decimals: " + format(round(prop("Number") * 100) / 100) +
7
"\n Three Decimals: " + format(round(prop("Number") * 1000) / 1000) +
8
"\n Four Decimals: " + format(round(prop("Number") * 10000) / 10000) +
9
"\n Five Decimals: " + format(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.
