Boolean
The value arguments of the IS functions are not converted. For example, in most other functions where a number is required, the text value 19 is converted to the number 19. However, in the formula ISNUMBER("19"), 19 is not converted from a text value, and the IsNumber function returns False.
The IS functions are useful in formulas for testing the outcome of a calculation. When combined with the IF function, they provide a method for locating errors in formulas.
