ISERROR
Tests for any error value.
Syntax:
ISERROR(value)
- Returns TRUE if value refers to or evaluates to any error value, including #N/A, and FALSE otherwise.
- Use the ISERR function to test for any errors except #N/A.
Example:
ISERROR(SQRT(-1))
- returns TRUE, because taking the squareroot of -1 is an error.
ISERROR(C5)
- where C5 contains 123, returns FALSE, because 123 is not an error.
ISERROR(NA())
- returns TRUE, because NA() returns the #N/A error.
Issues:
- CHOOSE(0;"A";"B";"C";"D") returns Err:502 (correctly - the index is out of range) but ISERROR(CHOOSE(0;"A";"B";"C";"D")) also returns Err:502, rather than TRUE. The error is propagated rather than evaluated.
