This describes the situation for Lua on RISC OS, which until recently 
was only implemented on systems without hard floats. The arrival of
the Raspberry Pi, the Beagleboard and others, promises better floating
point performance - when the C compilers available have caught up and
can cater for VFP2 (on the Raspberry Pi) and Neon. Then Lua 5.3 will
be a boon. However, I must confess that, as a pure rather than an applied
mathematician, I like to see types kept separate, with no implicit
coercions.
