Hello,
I was wondering how I could get a number from a cell, Lets say A1 = 3, and take another number, could range from 0 to 10, from D1 = 2, or something and take the value in A1 and turn it in .03 in cell C5, using VBA.
D1 is going to set the number of decimal places including the value in A1.
Examples
A1 3
D1 0
C5 3

A1 3
D1 4
C5 .0003

A1 3
D1 3
C5 .003

A1 3
D1 8
C5 .00000003

I know I could C5.formula and do all kinds of if statements, but I was hoping for more VBA simpleness.

Any help would be greatly appreciated.

Thank you in advance.

Re: Would like to add a specific number of decimals places before a number

Hello thank you for answering,

I'll play with the round and roundup, but I don't think they will do what I need to do. the numbers in A1 are just going to be a single number 1,2,3,5,8 etc I just need to turn them into a decimal based on the value in D1.
I could write about 10 if statements to taking the value in D1 and dividing A1 by a number 100,10,1000.
I was just hoping using vba would have a more simple way of doing that

Re: Would like to add a specific number of decimals places before a number

Does this formula do what you want...

=0+("."&REPT(0,D1-1)&A1)

Or if you are trying to change the numbers in place within the cells they appear in, the perhaps this macro does what you want...
Code: 
Sub MakeIntegersToFloatingPoint()
  Dim Addr As String
  Addr = "A1:A" & Cells(Rows.Count, "A").End(xlUp)
  Range(Addr) = Evaluate(""".""&REPT(0,D1-1)&" & Addr)
End Sub

Re: Would like to add a specific number of decimals places before a number

That does look like it might work, and .0007 would be correct I will have to wait till I get home from work this evening and add this to what I have been working and give it a try
Thank you I will let you know what I find out

Re: Would like to add a specific number of decimals places before a number

Wow that is a very tidy, and way less messy than what I would have wrote out.
It appears to do everything I need it to, except when I use "0" in D1, then I get a #value error. I don't think there would be a zero in D1, but there might be, its all user input

Re: Would like to add a specific number of decimals places before a number

if cells(2,1)=0,cells(1,1), Cells(1, 3) = Cells(1, 1) * 10 ^ -Cells(2, 1)

adjust for your cell locations

if it finds a zero it does not modify the number at all

For the formula...

For the code...
