the file oox/source/xls/formulabase.cxx has a section /** Functions
defined by OpenFormula, but not supported by Calc or by Excel. */
Does this refer to the draft ODF 1.2 formula spec?
No. I just scanned the function op-codes defined by sc (nowadays
formula/inc/formula/opcode.hxx).
Which functions are listed there? For example, why are the imaginary
functions and the secant functions not listed there?
This list in oox is not used anywhere.
So I need not worry about that file?
Sorry, just have taken a closer look. This table *is* used to preserve
Calc-only functions in roundtrip (save to Excel, load from Excel).
When reloading into my patched DEV300m76 I get this up to now, without
any entry in the files formulabase.cxx:
save in .sxc: All addin functions, including the existing ones, result
in #Name?, but the cell content contains the correct formula.
save in .xls: All addin functions are correct including the new ones,
all other functions unknown to Excel are shown with #MACRO?, but the
cell content contains the correct formula. For the Addin functions the
information in analysis_deffuncnames.src is used.
save in .xml: All functions have an additional of:]. Excel cannot read
the file. But that is not my fault, that is already broken in OOo3.2.
So I think, that using new Addin functions works well.
Gnumeric can read the ods file with all new functions, the "normal" and
the Addin function.
Same for the equivalent table "saFuncTable_Odf" in
sc/source/filter/excel/xlformula.cxx.
[..]
Just add the new functions to the tables. As Excel does not know them
(right?), the entries are used to create a unique function name in the
Excel file format (e.g. _xlfnodf.SEC), and the import filter will
restore the function known by Calc.
Will try the filter files tomorrow.
kind regards
Regina
