You don't need to switch Lua to floats to avoid this problem. If you
really want to keep DirectX as it is, you can recompile Lua to use the
default definition for lua_number2integer:

luaconf.h:544
- #if defined(LUA_NUMBER_DOUBLE) && !defined(LUA_ANSI) && !defined(__SSE2__) && \
-     (defined(__i386) || defined (_M_IX86) || defined(__i386__))
+ #if 0
