It picks the last two numbers in the stack, turns them into binary and returns a number made of their common cyphers. It is a bitwise operator
It can be useful to return looping series of numbers from a counter.
ANDing anything with 1 will tell you if it's a pair or odd number:
0 1 & = 0 1 1 & = 1 1 2 & = 0 1 3 & = 1 1 4 & = 0 1 5 & = 1
ANDing something with 2 will give you one positive value each two results:
2 2 & = 2 2 3 & = 2 2 4 & = 0 2 5 & = 0 2 6 & = 2 2 7 & = 2
ANDing something with 3 will loop results between 0 and 3.
3 0 & = 0 3 1 & = 1 3 2 & = 2 3 3 & = 3 3 4 & = 0 3 5 & = 1 3 6 & = 2 3 7 & = 3 3 8 & = 0
Starting from 0:
ANDing something with 4 returns:
0 0 0 0 4 4 4 4 0 0 0 0 and so on.
ANDing something with 5 returns:
0 1 0 1 4 5 4 5 0 1 0 1 and so on.
ANDing something with 6 returns:
0 0 2 2 4 4 6 6 0 0 2 2 4 4 6 6 and so on.
