I don't want to turn this into a heated argument but I'd like to
ask. Has anyone done profiling for Lua code that does a lot of
calculations and seen if there is any significant difference
between using doubles or ints on a Intel Pentium class processor?

Also is there any danger in compiling the lua interpreter to use
ints instead of double? I understand it's a compile time option.
