The behaviour of SUMPRODUCT() differs between 126.96.36.199 and 188.8.131.52
When the following formula is entered into cell A1 of a new, blank spreadsheet:
The following results are obtained:
The right hand argument ($C$1:$C$10="") should be true (=1) across the range of empty cells in column C, and previously an empty cell (column B) has always evaluated to "0" in this context, so each pair of column B and column C cells should evaluate to 0*1 = 0, not 1.
(This formula has been simplified from one in actual use in a much larger spreadsheet)
Hi Matthew, thanks for reporting.
There is an option in:
Menu/Tools/LibreOffice calc/Formula/Detailed calculation settings - Custom - Details - Treat empty string as zero.
Please verify if setting up to True solves your issue.

Thanks for the suggestion.
I'm afraid that option doesn't appear to make any difference to either the original spreadsheet or the simplified formula I reported. If it's supposed to then perhaps that should be looked at further.
I found a different workaround for the expression I need, which is to wrap the first argument with N(...) to cast the column values explicitly to numbers, which includes making "" equal to 0 (all the values in question are numbers or "").
If ""=1 is going to be the default in this context in future, I think it will make sense to stick with this, and adding the extra function doesn't appear to diminish the otherwise massive (and highly welcome) speedup I've seen with 4.2.
Seems a duplicate of bug 74479.
Please if you are not agree reopen it.
