Re: LNUM 2008 patch is ready :)

Do you need to suffix math functions with 'f' (s.a. 'floorf()',  
'powf()') or does your compiler use right ones without the suffix?

I think in the current unpatched Lua, functions actually work with  
double, and then scale down to storing as floats. Each system might be  
different, though.
