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.
