--- Comment #2 from Tomaz Vajngerl <quikee at gmail.com> ---
Nope, that's correct and expected. Calc (or better computers in general)
doesn't calculate with infinite precision (it uses floating points internally)
so there are cases, where a calculation will produce an (rounding) error. 

So in cases like this you need to round things to the nearest decimal (=ROUND)
- with that you also define how much precision you can tolerate.
