Perhaps the simplest data type, Booleans can only ever be TRUE or FALSE. They are key to logic within formulae.
Other data types are capable of emulating Booleans under the right conditions. We call these values ‘truthy’ and ‘falsy,’ as although they are not true Booleans, they function similarly.
When used in mathematical operations, Booleans will turn into numbers—TRUE becomes 1, FALSE becomes 0. When used in string operations, Booleans will simply turn into text versions of themselves (i.e. TRUE becomes “TRUE”).
Checkboxes will correspond with Boolean values by default.
