WebSep 29, 2010 · The union example you've posted doesn't do any ASCII conversion - you need to do that before you assign to the union's byte array, converting each ASCII hex digit to binary and shifting to the the appropriate place in the byte. system September 29, 2010, 8:45am #18. First off, it’s not Big Endian. WebEndianness. Endianness and endian are terms that describe the order in which a sequence of bytes is stored in memory. Big-endian is an order in which the most significant value in the sequence is stored first. In little-endian systems the least significant value in the sequence is stored first. For example, in a big-endian CPU, the four bytes ...
