Re: [Amforth] How to activate the floating point package

[pito <pi...@vo...>]

There is still a major issue with floating point, though. The
standard forth implementations require to have a separate floating
point stack (we do not have). So porting existing code to amforth
(ie scifi libraries) is difficult as you have to translate it to
none-fp-stack version - not easy, however..
Q to developers: would it be possible to introduce a fp stack? 32
cells deep would be enough, I guess..
