I'd like to see this solved with defines in a config, with something like

#define LUA_STRFORMAT_FLOATINGINT sizeof(int) < sizeof(lua_Number)
#if LUA_STRFORMAT_FLOATINGINT
#define LUA_STRFORMAT_INTEGER = "%.0f"
#else
#define LUA_STRFORMAT_INTEGER = "%d"
#endif

I've actually been impacted by this problem before, with large negative  
numbers (I solved it by changing "%d" to "-%d" and the input from v to -v).
