However, at this point I know that Pharo "does the right, raw, thing"
(at least compared to other mainstream languages), but it still

That's the "floating point surprise" that everyone has at some point, no

for you, are you sure that floating-point arithmetic is what you really
want? Maybe your needs are better served with integers and fractions.
