AtariWiki is very, very proud Newell Industries & Charles W. Marslett gave us the source code for the FAST FLOATING POINT routines for PD. Thank you so much Newell Industries & Charles W. Marslett, that is not a little gift, that is a giant leap for the community worldwide and will result in rewrite all Atari OS and burn them on EPROM. We further thank Robert 'Bob' Puff for converting the original [AMAC|https://atariwiki.org/wiki/Wiki.jsp?page=Atari%20Macro%20Assembler] source code into [MAC/65|https://atariwiki.org/wiki/Wiki.jsp?page=Mac65] source code and Konrad M. Kokoszkiewicz for finding the last remaining bug in the hexdgt routine: SBC $9 -> SBC #$9. Thank you all so much, the community is in great debt for the work you have done! :-)\\

!!Remark
drac030 from AtariAge found the last remaining thing to be changed in the hexdgt routine: SBC $9 should be changed into -> SBC #$9.
