in reply to first 5 bits and last 3 bits

This posting may win some sort of award for ambiguity. What do "first" and "last" mean? Are the "first" the most significant, and the "last" the least significant? If, as the OP added, "it's 8 bits", which 8 bits? The most/least significant? If you strip away leading 0's, as the OP did, is it the 8 bits whose most significant bit is a 1 (which, of course, may not yield 8 bits)? There are many reasonable suggestions here, just as there are many reasonable interpretations of what the heck the OP wants. It doesn't help that the OP offered several suggestions on what the result should be.

    It doesn't help that the OP offered several suggestions on what the result should be.

    He seems sure of 16, which is indeed the result one gets from taking the most significant 5 bits of an 8 bit number.

    As far as I'm concerned, this clears up the ambiguity, leaving a post that's simply unclear.
