VBA to 'breakdown' an integer into smaller integers

Hi Everyone,


I am looking for a VBA solution for the problem described below but I couldn't figure it out. Any help would be great!

The "Large Number" column and the "Component" column are the input and they are all integers. I was wondering if there is a VBA solution to "break down" the value in column "Large Number" into a number of smaller components based on the value in column "Component". The smaller integers should have variations in their sizes rather than integers closed to the quotient of Large Number and Component, and they will need to add up to the Large number. Thanks.

The actual table has quite a few more rows than the two rows shown below.

Table with Input
[TABLE="class: grid, width: 500, align: left"]
<tbody>[TR]
[TD]Large Number[/TD]
[TD]Component[/TD]
[/TR]
[TR]
[TD]375[/TD]
[TD]3[/TD]
[/TR]
[TR]
[TD]450[/TD]
[TD]6[/TD]
[/TR]
</tbody>[/TABLE]









Table with Output
[TABLE="width: 439"]
<tbody>[TR]
[TD][TABLE="class: grid, width: 500, align: left"]
<tbody>[TR]
[TD][TABLE="width: 95"]
<tbody>[TR]
[TD="class: xl65, width: 95"]Large Number[/TD]
[/TR]
</tbody>[/TABLE]
[/TD]
[TD]Component[/TD]
[TD][TABLE="width: 272"]
<tbody>[TR]
[TD="class: xl65, width: 272"]Smaller Number (The Output column)[/TD]
[/TR]
</tbody>[/TABLE]

Hi footoo,

It is working now, thanks a bunch for that.

I don't have data after column D.

Hi footoo,

I have the above code and when it encounters the following data point, it produced a run time error on line

"cel(1, 4).Resize(, Columns.Count - 2).ClearContents"

[TABLE="class: grid, width: 500, align: left"]
<tbody>[TR]
[TD]Item[/TD]
[TD]Nature[/TD]
[TD]Large Number[/TD]
[TD]Component[/TD]
[/TR]
[TR]
[TD]XXX[/TD]
[TD]YYY[/TD]
[TD]18[/TD]
[TD]6[/TD]
[/TR]
</tbody>[/TABLE]






Not sure if this is the exact line of the bug though...

Lock one reference in a formula
Need 1 part of a formula to always point to the same range? use $ signs: $V$2:$Z$99 will always point to V2:Z99, even after copying

Hi,

I think it is just that there is no solution for 6 integers to make up a total of 18 without duplicating some of them.

Under this kind of circumstance, what error catching mechanism would be easier to implement? For instance just to allow a single duplicate within the set of small integers may be? Thanks.

regards,
Ryu

When the change was made to switch from column A to column C, I overlooked to change this line.
Change it to :
Code: 
cel(1, [COLOR=#ff0000]3[/COLOR]).Resize(, Columns.Count - [COLOR=#ff0000]cel.Column-1[/COLOR]).ClearContents

Under this kind of circumstance, what error catching mechanism would be easier to implement? For instance just to allow a single duplicate within the set of small integers may be?

At present the code highlights the cells and doesn't display anything in column E.
Will look at creating small integers and restricting to minimum duplicates - later.

New version below.
The highlighted cells in column E will contain duplicate numbers. You might want to review and amend manually.
Code:

        GoTo n
    ElseIf cel(1, 2) = 1 Then
        cel(1, 3) = cel
        GoTo n
    End If
    avg = Int(cel / cel(1, 2))
    s = 0
    t = 0
    ReDim ray(1 To cel(1, 2))
    For i = 1 To cel(1, 2)
        ray(i) = Rnd * avg + 1
        s = s + ray(i)
    Next
    ReDim rayT(1 To cel(1, 2))
    For i = 1 To cel(1, 2)
        rayT(i) = Round(ray(i) * cel / s, 0)
        t = t + rayT(i)
    Next
    If t < cel Then
        rayT(1) = rayT(1) + cel - t
    ElseIf t > cel Then

    For b = a + 1 To UBound(rayT)
        If rayT(a) = rayT(b) Then Dup = True: Exit Function
