I am badly curious - so I sometimes cross check with other Smalltalk80
versions. I hope that is not a betrayal.

I found that classes in a GNU Smalltalk-80  documentation
http://www.gnu.org/software/smalltalk//manual-base/html_node/FloatD.html. I
was not aware that this was a GNU Smalltalk docu.

But that classes do have some interesting methods.
