Have you ever had to use bit shifting in real projects?

Question

Have you ever had to use bit shifting in real programming projects? Most (if not all) high level languages have shift operators in them, but when would you actually need to

Answer 1

Yes, when performing binary communication between Java and C# applications, one is big-endian byte ordering and the other is little-endian (not necessarily on this order). I created an InputStream class that could read numbers with a different byte order, and it used byte-shifting in order to work.

Sometimes also when you want to put 4 shorts in the 4 bytes of a long, it would be case the of using byte shifting. I think I did that many years ago...
