Hi Matthias, yea, you both share Leon's code (in some stripped down version w/ FF), which is neither amforth nor FF related. Otherwise the FF floating point follows the other approach - it calls C math functions, and the current implementation of that stuff comes from https://github.com/igor-m/Floating-Point-Library-for-FlashForth with some minor edits, mostly with FOR introduction (instead do-loop) and >float support. FF's fp ran succesfullly in sommer 2014 aleady (without recogniser), but there was no time to propagate that stuff to the FF folk..
I've done a short mailing with Leon these days, trying to sell him an idea of double precision implementation. Too busy however. I do not have any ready-to-run amforth hw these days (only a single dsPIC33 for FF), but you may try to flash it, the stuff is maybe 4kB big, I did it with 1284p and it worked fine. It fits 328 sure. I've added a big test file there, it will test almost everything from the library, you may see the precise results printed for a comparision, the numbers I gathered during a long winter evenening (which year?).
