Asko Kauppi has a patch to Lua that allows it to use a combination of 
number representations depending on what's appropriate at the time. Look 
for LNUM here:

That way you get integer speed when doing integer arithmetic, and it'll 
automatically fall back on floats when needed, but only when needed. The 
best of both worlds, really.
