Hi all,
thinking about issue 102980 and 102981 I found, that it is not clear to
me, how to calculate MULTIPLE.OPERATIONS at all.
Take a spreadsheet and enter the following numbers and formulas into
column A, beginning in cell A1 with number 2.
2
3
=A1+A2
30
=MULTIPLE.OPERATIONS(A3;A2;A4)
700
=MULTIPLE.OPERATIONS(A5;A2;A6)
What do you expect in cell A7? OOo3 calculates the value 702.
In ODF1.2 draft spec I read, "MULTIPLE.OPERATIONS executes the formula
expression pointed to by FormulaCell and _all_ formula expressions it
depends on while replacing _all_ references to RowCell with references
to RowReplacement respectively all references to ColumnCell with
references to ColumnReplacement."
I think that the terms "execute formula expression" and "while
replacing" is not exact enough.
(1) I interpret it in the way, that I first replace all references,
generating intermediate, temp sheets, and then evaluate that sheet. I
get the following:
For =MULTIPLE.OPERATIONS(A5;A2;A6) we have to replace in the content of
A5 all references to A2 with A6. So content of A5 becomes
=MULTIPLE.OPERATIONS(A3;A6;A4).
But A3 is not a finite number but a formula which depends on A1 and A2.
Therefore in A3 the reference A2 is also replaced with A6 and the
content of A3 becomes =A1+A6.
Our new sheet content with replaced references is now:
2
3
=A1+A6
30
=MULTIPLE.OPERATIONS(A3;A6;A4)
700
With this sheet we have to take the value of A5 as result for A7.
Calculating the value of A5 we have to execute a MULTIPLE.OPERATION. It
says that the reference A6 in the formula in A3 is to be replaced with
the reference A4.
We get the next temp speat content:
2
3
=A1+A4
30
700
with the inner-outer-order of calculating A3 then A5 then A7. So the
shown values are
2
3
32 //result of =A1+A4
30
32 //result of A3
700
32 //result of A5
(2) I replace the reference in the formula expression referenced by
FormulaCell and then immediately execute that expression.
For =MULTIPLE.OPERATIONS(A5;A2;A6) we have to replace in the content of
A5 all reference to A2 with A6. So content of A5 becomes
=MULTIPLE.OPERATIONS(A3;A6;A4). This results in the sheet
2
3
=A1+A2
30
=MULTIPLE.OPERATIONS(A3;A6;A4)
700
Calculating the result of A5 we have to replace all references A6 in
cell content A3 with A4. This results in the sheet
2
3
=A1+A2 // There is no A6 reference
30
700
We calculate the results in inner-outer-order first A3 then A5 then A7,
and get the sheet
2
3
5 //result of A1+A2
30
5 //result of A3
700
5 //result of A5
Mmh, neither (1) nor (2) results in 702.
kind regards
Regina
