I96 or I128, 12 or 16 bytes literal

[lavalava]

Hi, guys.  Let's say I have an array of 8 bytes and cast it to an I64, I can do it like this:

Now, I have a 12 bytes array and want to cast it to at least a 12 bytes literal, how do I do that?  This could be either integer or unsigned integer.  Is there such thing as a 12 bytes or 16 bytes literal in LV?

Also, quick question ....an I16 takes 2 bytes.  Does that mean a U16 take a 2 bytes of memory also?

Hi lavalava,

"an I16 takes 2 bytes.  Does that mean a U16 take a 2 bytes of memory also?"

Yes. As is written in the LabVIEW documentation...

"Is there such thing as a 12 bytes or 16 bytes literal in LV?"

Well, one could mention a timestamp consisting of 128 bits (or 16 bytes), but does it count for your purpose? I would opt for answer "No"...

There are no 12 or 16 byte data types in LabVIEW.  (Thought there is one exception.  The timestamp is 128-bit or 16 bytes)

Yes.  A U16 and an I16 both take up 2 bytes.

I guess I'll settle for 8 bytes (I64) then.  Oh well.  Yes, I do need it as an integer.

You could simply make your own. This is essentially what was done prior to the availability of native 64-bit integers. For example, for the 16-byte case create a cluster that consists of the "high" part (8 bytes) and the "low" part (8 bytes). Or you could create a "high", "middle", and "low" (e.g., using I32 for the 12-byte case with 3 I32s).
