Bitwise operations takes in 1-2 integer(s) and returns the result of
taking an operation on every binary digit (except shifts).

Bitwise and (&)
-14 & 23
= 0b110010 &
  0b010111
= 0b010010
= 18

Bitwise or (|)
-14 | 23
= 0b110010 |
  0b010111
= 0b110111
= -9

Bitwise not (~)
~23
= ~0b010111
=  0b101000
= -24

Bitwise xor (^)
-14 ^ 23
= 0b110010 ^
  0b010111
= 0b100101
= -27

Left shift (<<)
-14 << 2
= 0b  110010 << 2
= 0b11001000
= -56
The bits on the right is filled with 0s.

Arithmetic right shift (>>, >>> in some languages)
-14 >> 2
= 0b110010 >> 2
= 0b111100
= -4
23 >> 2
= 0b010111 >> 2
= 0b000101
= 5
The fractional part is ignored and the bits on the left are filled
with 0s or 1s, depending on the sign of the input.

Logical right shift (>>> in some languages)
-14 >>> 2
= 0b110010 >>> 2
= 0b001100
= 12
23 >>> 2
= 0b010111 >>> 2
= 0b000101
= 5
The fractional part is ignored and the bits on the left are filled with 0s.
