pranav:
The link you copied from Steves old posts is no longer good. But thanks anyways. I got the idea to use "FP52" and "FP51" as search keys in Google and located FP51 at the Philips web site. So thanks!!

I appreciate your input. I normally solve the problem of fractional arithmetic in the way that you show in your post. Unfortunately the application I have at hand will, I believe, require a full float implementation. At least now I have it and can try it out. The issue of the assmebler not supporting the number storage format is not important to this application. The numbers start out 32 bit binary and end up with over 7 digits of significance. Unfortunately the application also has those 7 digits of significance over a range from 10E3 to 10E-4. Thanks again.
