Excel 2007 : Help needed to write a subtraction formula

I'm trying to write a formula that will deduct one number from another with varying decimal places to achieve a positive number result. e.g.

1.32650 - 1.32750 = 10
or
1.32750 - 1.32650 = 10

and

75.250 - 75.150 = 10
or
75.150 - 75.250 = 10

The answers shown above are what I need to achieve.

Attached is what I have so far, however I have to adjust the formula each time depending on whether I'm subtracting three or five decimal places.

This has plagued me for weeks, any assistance would be greatly appreciated.

Thanks in advance, FXtrader
