Re: better float2str() C code, anyone?

All I want to please is the Lua engine itself, really, and for that 
this code (bugs aside) seems sufficient. It goes hand-in-hand with the 
two places where I suggested using 'number2str()'.

I'd be delighted if my little codie gets into the 'etc/' or something 
in future Lua. :)
