# Boolean or truth values

A Boolean or truth value can be True and False, or, equivalently, the number 1 or 0. For example:

False OR True → True
1 AND 0 → False
1 OR 0 → True

It actually treats every nonzero number as True. For example:

2 AND True → True

Boolean values are represented internally as the numbers 1 and 0. By default, a Boolean result displays as 0 or 1. To display them as False or True, change the number format of the variable to Boolean (see Number formats).
