You need to look at the typecast node. Whenever you are pulling
back binary data and need to look at as another type of binary,
then
consider using typecast. If the data is coming back as
formatted data, then use a Scan From String.
To go the other way, use typcast to make the binary data and
use Format into String.
In this case, cast it as an array of I16 or U16. Depending
on the byte ordering, you might need to use the swap bytes to
reorder the bytes.
