I saw a great discussion on this issue before...try searching the
archives.

A quickie fix might be in Documentation/Docbook/Kernel-hacking.html
Search for "Some Basic Rules"...

Best Advice:  resign yourself to writing floating point into the
kernel...or doing without.

P.S.  I've implemented a neural net.  Very cool fun!  Good luck Lars!
