The main change in Lua 5.3.0 is support for integers.

I played around with this a bit. The only thing I found that appears to be missing is the ability to determine the actual type of the number. That is:

    a = 5
    ttype(a) == 'number'

    b = 5.0
    ttype(b) == 'number

From the C API, it appears that lua_isinteger() will work for the 'a' case.

It would be nice if there was a method to do so in Lua itself. One use case is for serializing integer values to disk in text form properly.
