| Formula | Description | Result | Expected | Verdict |
|---|---|---|---|---|
| =ISERROR(1/0) | ISERROR is TRUE for a #DIV/0! error, one of ANY error type it catches (per support.microsoft.com/en-us/office/is-functions-0f2d7971-6019-40a0-a171-f2d869135665) | True | True | Matched |
| =ISERROR(NA()) | ISERROR is also TRUE for #N/A specifically (unlike ISERR, which excludes #N/A) -- contrast with ISERR_na and ISNA_na in the sibling test files | True | True | Matched |

| =ISERROR(5) | A plain non-error number -> FALSE | False | False | Matched |
