Difference between "cast" and "unflatten from string" functions

[ENSTB_Vivien]

Hello,

I don't see the advantages to use one function or the other, they do the same no?

Maybe I'm tired...

Thanks.

Hi Vivien,

well, 'type cast' takes any input datatype while 'unflatten from string' requires a string input

With 'type cast' you can transform one datatype to a completely different (by using a new interpretation of the bit- or bytestream).
'Unflatten' tries to recognize LabView datatypes...

Ok, thanks a lot, I was only puting a string in input so I haven't noticed it...

Another question, both functions have the same speed?

You should benchmark it yourself to be sure. Both are very fast and so speed is not much of an issue anyway. 😉

Unflatten from string has received quite a few modifications in newer labview versions, for example it can now deal with byte order (little/big-endian) and with datatypes that include size information. It is much more flexible IF you need all that. 🙂
