For us pros it gets far worse than that. In my working days often had to 
compute the "fuzz" value to use in comparisons because of "rounding 
errors" when the two amounts being compared came from different 
calculations. The "fuzz" is the maximum amount of difference that could 
have caused. So you can't test for "equal" but need to test for equal 
+/- fuzz.
