Like it was just mentioned by someone else, one example would be the
Playstation 2 game console. It's hardware supports floats but not
doubles. If any instruction uses doubles then the calculations are
emulated in software and are then really slow.
The only problem i can see with using floats is that it then becomes
imposible to represent 32 bit integer values in Lua.
