I have two variables: x and y

x&=~y

I don't understand what the ~ operator is doing their. I know the XOR OR and AND binary operators. But the not the NOT operator. I'd appreciate an example and/or an explanation.

It's the binary opposite.

So. if y=2 - 10.
Then. x = x & 1(or 01)

Is that correct?

Actually, it's more along the lines of x = x & 65533 (1111111111111101)

Interestingly, the ~ operator doesn't handle decimals at all. ~1 == ~1.1
