"NO LOSS" ?

Don't forget that this theory is only valid if you have an infinite bit resolution,
which is not the case in practice.
If you calculate it in a math lesson with floating decimal point numbers, everything
is O.K., but if you have to use ordinal numbers like A/D converters, you are a little
bit away from the theory...
