Of course some targets might not be able to use it due to memory constraints, but this is secondary. Many would benefit from it. > Exactly my thoughts. One routine works on all 6502-platforms. I don't care about the "best", except one is noticeably faster. I would give up precision for speed any time. The ATARI-rom is using 6 byte BCD numbers. If there really is an interest I can look more into the specifics. However, I have (yet) no clue how to support FP in a compiler. Things which spring to mind are: - constant parsing - argument pasing (on stack) - type conversions I guess Uz has a bit more knowledge on that topic :) Would IEE754 compatibility be satisfied enough, when we use (single) floats, convert them to the internal representation and convert the result back to single precision float? salut, daniel ---------------------------------------------------------------------- To unsubscribe from the list send mail to majordomo@musoftware.de with the string "unsubscribe cc65" in the body(!) of the mail.Received on Thu Apr 29 08:28:01 2010
