Maybe I'm missing something but I can't find a straightforward way to accomplish this simple task. When I go to negate a binary number through the "~" operator it returns a negative number due to the two's complement:

```
>>> bin(~0b100010) # this won't return '0b011101'
'-0b100011'

```

What about if I just want to switch 0s into 1s and vice-versa, like in classic logical complement?
