Explanation…

I have a filed of data formatted as number, I need it as number coze it has
to add up on some other reports and forms that I have (if not formatted as
number then formulas will not work). My only question is, I need numbers
entered in this filed to be displayed the way I enter them.
i.e:  if 2.5 then show 2.5 not 2
       if 2.30 the show 2.30 not 2.3 nor 2
       if 10 then show 10 (which is good in this case)
       if 100.25 then 100.25 not 100 nor 100.2
basically, I need them to be displayed exactly the way I enter them.
I have searched and find something similar but not anything that could sort
this problem. I’ve also manipulated with decimal places etc… they failed, too.
