Example | Name | Result

$a & $b | And | Bits that are set in both $a and $b are set.
$a | $b | Or | Bits that are set in either $a or $b are set.
$a ^ $b | Xor | Bits that are set in $a or $b but not both are set.
~ $a | Not | Bits that are set in $a are not set, and vice versa.
$a << $b | Shift left | Shift the bits of $a $b steps to the left (each step means "multiply by two")
