Would someone kindly explain to me what is going on here. All I can
see
is even numbers return a '0' and odds a '1'. I also know all even
numbers in binary end in a zero. I had thought '&' was another way
of
writing the 'and' operator, seems I was wrong.
This is a bitwise AND, ie it operates on each of the binary bits
independanly. OTOH The logical AND operator treats the value
*as a whole* as a boolean (true/false) value and operates
on that value.
You can read about bitwise operators and how and why they are used
in my tutorial in the Using the OS topic, about half way through.
HTH,
