    WSLUA_MODULE Int64 Handling 64-bit Integers

    Lua uses one single number representation which can be chosen at compile time and since it is often set to IEEE 754 double precision floating point, one cannot store 64 bit integers with full precision.

    Lua numbers are stored as floating point (doubles) internally, not integers; thus while they can represent incredibly large numbers, above 2^53 they lose integral precision -- they can't represent every whole integer value.
    For example if you set a lua variable to the number 9007199254740992 and tried to increment it by 1, you'd get the same number because it can't represent 9007199254740993 (only the even number 9007199254740994).

    Therefore, in order to count higher than 2^53 in integers, we need a true integer type.
    The way this is done is with an explicit 'Int64' or 'UInt64' object (i.e., Lua userdata).
    This object has metamethods for all of the math and comparison operators, so you can handle it like any number variable.
    For the math operators, it can even be mixed with plain Lua numbers.

    For example 'my64num = my64num + 1' will work even if 'my64num' is a <<lua_class_Int64,`Int64`>> or <<lua_class_UInt64,`UInt64`>> object.
    Note that comparison operators ('==','$$<=$$','>', etc.) will not work with plain numbers -- only other Int64/UInt64 objects.
    This is a limitation of Lua itself, in terms of how it handles operator overloading.

    // Previous to Wireshark release 1.11, Int64 and UInt64 could only be created by tvbrange:int64() or tvbrange:le_int64(), or tvbrange:uint64() or tvbrange:le_uint64() or tvbrange:bitfield(), and had only a couple functions (the metamethods tostring() and concat()).
    // All of the functions on this page are only available starting in Wireshark 1.11 and higher.

    [WARNING]
    ====
    Many of the UInt64/Int64 functions accept a Lua number as an argument.
    You should be very careful to never use Lua numbers bigger than 32 bits (i.e., the number value 4,294,967,295 or the literal 0xFFFFFFFF) for such arguments, because Lua itself does not handle bigger numbers consistently across platforms (32-bit vs. 64-bit systems), and because a Lua number is a C-code double which cannot have more than 53 bits of precision.
    Instead, use a Int64 or UInt64 for the argument.
    ====

    For example, do this...

    [source,lua]
    ----
    local mynum = UInt64(0x2b89dd1e, 0x3f91df0b)
    ----

    ...instead of this:

    [source,lua]
    ----
    -- Bad. Leads to inconsistent results across platforms
    local mynum = UInt64(0x3f91df0b2b89dd1e)
    ----

    And do this...

    [source,lua]
    ----
    local masked = mynum:band(UInt64(0, 0xFFFFFFFF))
    ----

    ...instead of this:

    [source,lua]
    ----
    -- Bad. Leads to inconsistent results across platforms
    local masked = mynum:band(0xFFFFFFFF00000000)
    ----
