If you need floating point numbers the leJOS JVM for the RCX uses floating
point:

http://lejos.sourceforge.net

This seems like a very intersting idea. I actually wanted to skip the RCX
altogether and somehow link up a networking protocol using just the IR
Towers. One computer could communicate with another and you could even throw
in some encryption so no one else could intercept it.
