Here is the data:

C F I J N O
1.17 4.45 2.79 7.24 8.47 8.47
1.23 2.12 2.12 2.61 2.61

7.81

7.81 is the sum of values in col F multiplied by their corresponding
value in col C.
So 7.81 should equal (1.17 * 4.45) + (1.23 * 2.12)
ie 5.2065 + 2.6076 = 7.8141 round to 7.81

However, I need each multiplication to round. So
1.17 * 4.45 = 5.2065 = 5.21 and
1.23 * 2.12 = 2.6076 = 2.61
thus 5.21 + 2.61 = 7.82

Here's the code that currently sums the column:

For ColNdx = 5 To 9 'cols E to I
Cells(EndToCollectionRow - 1, ColNdx).FormulaArray = "=SUM((" & Range( _
Cells(StartToCollectionRow, "C"), Cells(EndToCollectionRow - 2, "C")) _
.Address & ")*(" & Range(Cells(StartToCollectionRow, ColNdx), _
Cells(EndToCollectionRow - 2, ColNdx)).Address & "))"
Cells(EndToCollectionRow - 1, ColNdx).Value = _
Cells(EndToCollectionRow - 1, ColNdx).Text
Next ColNdx

Is there a way to modify the code, please?

Regards.

You could apply the ROUND statement for the sum.

round (sum();2)

I didn't test it.
Let us know.

Ciao Alex.

ie 5.2065 + 2.6076 = 7.8141 round to 7.81

Thanks, but I think the chance to Round has passed by the time
the value hits the Sum cell.
I guess I need to find a way to Round each calculation BEFORE
its' result is added to the Sum....if you see what I mean.

Sorry Stuart,

round globally the product this way

.....formularray = SUM(ROUND(array1*array2;roundoff))

Choose the round off you desire.

I tested this formula manually in a worksheeet and Excel allows it.

Let us know.

Alex.

Have amended to:

For ColNdx = 5 To 9 'cols E to I
Cells(EndToCollectionRow - 1, ColNdx).FormulaArray = "=SUM(ROUND(" &
Range( _
Cells(StartToCollectionRow, "C"), Cells(EndToCollectionRow - 2, "C")) _
.Address & ")*(" & Range(Cells(StartToCollectionRow, ColNdx), _
Cells(EndToCollectionRow - 2, ColNdx)).Address & "), 2)"
Cells(EndToCollectionRow - 1, ColNdx).Value = _
Cells(EndToCollectionRow - 1, ColNdx).Text
Next ColNdx

and get "Unable to set the FormulaArray property of the Range class" error.

Did I miscode your suggestion?

Regards and thanks.

What kind of testing have you done Stuart?

Sub Tester9()
starttocollectionRow = 1
Endtocollectionrow = 8
colndx = 3
sStr = "=SUM(ROUND(" & Range( _
Cells(starttocollectionRow, "C"), Cells(Endtocollectionrow - 2, "C")) _
.Address & ")*(" & Range(Cells(starttocollectionRow, colndx), _
Cells(Endtocollectionrow - 2, colndx)).Address & "), 2)"
Debug.Print sStr
End Sub

produces

=SUM(ROUND($C$1:$C$6)*($C$1:$C$6), 2)

so you have clearly miscoded it since this formula is in error.
