I found that there are some Float-Subclasses: FloatD FloatE FloatQ How can I use them and what are they good for? I do not understand the use of LargeZeroInteger as well.
Squeak does not have these classes. In fact, most Smalltalks do not, even though it is part of the ANSI standard. The only numeric classes that are part of the regular image are Float, Fraction and Integer, with its subclasses LargePositiveInteger, LargeNegativeInteger, and SmallInteger. There are other numeric classes out there, such as Complex, but these are the ones that get used by everybody.
It has been a while since I have used VisualWorks. It has a fixed decimal number, in addition to the ones I just mentioned. But I don't think it has the subclasses of Float, either.
