As we are migrating a DOS 6.1 app over to windws 7.6, we noticed a 
difference with a computed column.

S_Amt  =  (S_Qty * S_Unit)
S_Amt is Currency
S_Qty is Integer
S_Unit is Double

As an example, 
S_Amt = 20389 * 0.565  

On a calculator, the answer is 11519.785

The computed column in DOS 6.1 shows 11519.78
The computed column in Windows 7.6 shows  11519.79

Obviously the 7.6 answer is "right".  Turns out the client was 
undercharging their customers by .01 on these types of amounts, and the 
customer would 
have paid 11519.78.  But if they make any change to the row in windows 7.6, 
it recalculates that s_Amt column, it increases by .01, and now the balance 
due is .01!   

Does anyone remember this being a difference between older versions and 
newer versions?   Just looking for a clue as to why/when this behavior changed. 
 I'm assuming there's no way to change 7.6 so that it behaves like 6.1, 
even if it's "wrong"?   The problem we're having is that a user can make a 
change to the row's data in either DOS or Windows as we migrate, and that 
changes this amount back and forth!!
