	Yes, the SubLogic FlightSimulator uses *only* integers, and 16 bit
ones at that. The code that drives it is highly optimized (Bruce Artwick,
the president and primary programmer/designer of the simulator is a true
assembler God). In many cases, however, it gets the "wrong" answer, but
it takes advantage of the facts that 1) if you are generating several frames
per second, messing up one is not a big deal and 2) if the user doesn't notice
it doesn't really matter. I believe that the company sells a programming
package called "IB3D1" which allows you to use the core of the F.S. to do
your own graphics. The company is located in Champaign IL (or possibly
Urbana - they are really 1 city, and I think there are actually SubLogic
offices in both places). I worked there last summer, so I got to use
stuff without having to pay for it.
