# Boolean

The Boolean Data Type has two potential values: `TRUE` and `FALSE`. It used to answer "Yes"/"No" questions. For example, a Checkbox component uses a Boolean value to determine whether or not it should be displayed with a check or not.

Booleans are also useful for the conditional **IF** function. For example, the function **ISNUMBER** will return `TRUE` if the argument is a Number Type, and `FALSE` otherwise. One can use this function combined with **IF** to conditionally perform some operation depending on if a value is a Number:

```javascript
IF(ISNUMBER(my_variable), FORMAT_NUMBER(my_variable, "#"), "Not a number")
```
