ISLOGICAL

Formulas / ISLOGICAL
Test if a value is logical.
=FALSE
  • value - required argument that can be a blank cell, error, logical value, text, number, or reference value

Examples

    This example uses the ISLOGICAL function to evaluate the logical value TRUE. The ISLOGICAL function takes in one argument, in this case the logical value TRUE, and returns the logical value TRUE. This is because TRUE is a logical value and ISLOGICAL will return TRUE as a result.

    This example uses the ISLOGICAL function to evaluate the logical value FALSE. The ISLOGICAL function takes in one argument, in this case the logical value FALSE, and returns the logical value TRUE. This is because FALSE is a logical value and ISLOGICAL will return TRUE as a result.

    This example uses the ISLOGICAL function to evaluate a cell in a worksheet. The ISLOGICAL function takes in one argument, in this case the cell A2, and returns the logical value TRUE if the cell contains a logical value, or FALSE if the cell does not contain a logical value. For example, if A2 contains the logical value TRUE, then ISLOGICAL will return TRUE as a result.

    This example uses the ISLOGICAL function to evaluate a text string. The ISLOGICAL function takes in one argument, in this case the text string "TRUE", and returns the logical value FALSE. This is because the text string "TRUE" is not a logical value and ISLOGICAL will return FALSE as a result.


Summary

The ISLOGICAL function returns TRUE if the argument is either TRUE or FALSE, and FALSE for any other value. It accepts one argument, either a cell reference, formula or hardcoded value.

  • The ISLOGICAL function returns TRUE if a cell contains a logical value of TRUE or FALSE and FALSE for cells that do not contain logical values.
  • The ISLOGICAL function takes one argument, which can be a cell reference, a formula, or a hardcoded value.
  • When the argument is a logical value, the function returns TRUE; when the argument is not a logical value, the function returns FALSE.
