WebApr 18, 2012 · The & Operator. Up first: the bitwise AND operator, &. A quick heads-up though: normally, ints and uints take up 4 bytes or 32 bits of space. This means each int or uint is stored as 32 binary digits. For the sake of this tutorial, we'll pretend sometimes that ints and uints only take up 1 byte and only have 8 binary digits..
