Learn about the Number data type in Notion formulas.

The Number data type holds and represents numbers. Numbers can be used with mathematical operators such as add + and divide / to perform mathematical operations and calculations.

2 + 2 /* Output: 4 */

6 / 2 /* Output: 3 */
Code language: JavaScript (javascript)

Mathematical operations follow the standard mathematical order of operations (PEMDAS).

3 + 4 * 5 /* Output: 23 */

(3 + 4) * 5 /* Output: 35 */
Code language: JavaScript (javascript)

To learn more, see the guide on operator precedence and associativity:

Notion will automatically convert numbers with more than 21 digits to scientific notation when displayed in the formula property, but will display the full number in the formula editor:

See this in action in this example database:

Notion – The all-in-one workspace for your notes, tasks, wikis, and databases.
A new tool that blends your everyday work apps into one. It’s the all-in-one workspace for you and your team

Numbers will automatically be converted to strings if they are combined with other data types.

"There are " + prop("Members").length() + " members."
/* Output: "There are 12 members." */

["There are", prop("Member"),"members."].join(" ")
/* Output: "There are 12 members." */
Code language: JavaScript (javascript)
