Boolean value

A Boolean value is a logical TRUE (1) or FALSE (0) value, an expression that evaluates to a Boolean value, or a reference to a cell containing or evaluating to a Boolean value. It is generally the result of evaluating a Boolean expression, but a Boolean value can be specified directly as an argument to a function or as the content of a cell. A common use of a Boolean value is to determine which expression is to be returned by the IF function.
