Yes that is correct, so 2 will be integer and 5.3 float, operations will be defined in terms of how they convert, so there will be int and float division. The draft manual is here http://www.lua.org/work/doc/manual.html (see 3.4.1). This will not happen for a while, but it will make it much easier in future for interfaces like the kernel that need 64 bit int support, which is why it is being implemented. So not being compatible with this seems a mistake. Justin
