In <1306@gmdzi.UUCP>, Georg Wittig (wittig@gmdzi.UUCP) requests Z80
algorithms for 16- and 32-bit arithmetic, code conversion, etc.

Georg-
   There's a pretty good book on the subject called "Z80 Assembly Language
Routines" by Lance Leventhal and Winthrop Saville (Osborne/McGraw-Hill,
Berkeley, 1983).  I don't know if it's still in print (soft-bound), but
perhaps you could find it in a good library??  It presents assembly language
fragments with descriptive text in chapters with titles such as:  "code
conversion", "string manipulation", "arithmetic", "bit manipulation and
shifts", etc.  I can't vouch for the relative speed of these algorithms,
but it certainly could be a good place to start!  If you are interested
in floating point arithmetic, there's not much here.  You might then try
looking at a dis-assembled BASIC or f.p. math libraries from a Z80 "C"
compiler??  Any help with f.p. out there????
