Can anyone please help.

I am trying to write a very simple macro that will just edit a cell and
delete the last chracter.
Example:
I have a column with the following numbers:
1234
5678
9032

I want a macro that I can just convert each cell to the following:
123
567
903

Therefore, stripping the last digit. I don't even mind if it splits the cell
into two so the end result is:
123 4
567 8
903 2

Thank,
David
