Created attachment 32596 [details] Patch archive The attached patch contains support for the ISERR Excel function. https://support.office.com/en-ca/article/ISERR-function-833ae773-18c4-4c0e-b850-33a305b856e1 ISERR is similar to the ISERROR function, except that it does not count a value of #N/A as an error, whereas ISERROR does. Also, in the diff some of the empty whitespace in FunctionEval.java has been removed. Thanks, Conor
