Reverse the elements of a byte array and pack them into an int WebByte packing and unpacking is used mostly for communications between a xPC Target and another device, over Ethernet for example. If bytes are coming in, they can be condensed into other data types such as singles or doubles. Conversely, if you are sending out doubles or singles, often you need to separate them into bytes first. Share
