Hi,
I just finished going through tutorials at http://exagone.cjb.net, and briefly skimmed some of the other ones which are available on Iczelion's site. One thing I didn't see was information on how to use floating point numbers and how to perform basic calculations like logarithms, trig functions, etc. Is there a tutorial that I missed which has this information?
Thanks for any advice and for the terrific site.

floating point calculation is done by 8087 co-processor
basic commands are in www.intel.com
(search for 8087, 80287, 80387)
8087 uses 8 stacks
all command begins with 'F'
FLD(load) FSTP(store) etc..

Download chapter 14 of the Art of assembly Langage, it explains floating instructions.
