The Boolean Data Type has two 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:

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