I think I get some geek points.

The floating point libraries that came with my 8051 C compiler aren't giving me the realtime speed that I need.  I just sat down and wrote a new floating-point multiply that executes in 60% of the time of the stock algorithm, at the cost of half a mantissa LSB in precision.  Quite incredibly, it even seems to work!

Next up, addition.
