Undocumented Behavior of Standard Functions

Microsoft Excel allows certain undocumented argument constructs for standard functions. Some of these constructs that were previously unsupported in Extreme speed are now allowed, for example:

=SUMPRODUCT(A1:A10*B1:B10)
=SUMPRODUCT(A1:A10/B1:B10)

However, some of these argument constructs are still not supported in Extreme speed and will be flagged as incompatible:

Example message: "Unsupported Microsoft Excel or Crystal Ball function at cell location [Book1.xls]Sheet1!A1. (Code #5539)"
Workaround: For best results, always use standard syntax with fully valid arguments.
