ISERR
Tests for an error value other than #N/A.
Syntax:
ISERR(value)
- Returns TRUE if value refers to or evaluates to an error value other than the Not Available error #N/A, and FALSE otherwise.
- Use the ISERROR function to test for any errors including #N/A.
Example:
ISERR(SQRT(-1))
- returns TRUE, because taking the squareroot of -1 is an error.
ISERR(C5)
- where C5 contains 123, returns FALSE, because 123 is not an error.
ISERR(NA())
- returns FALSE, because the error value #N/A is ignored by this function.
