Bitwise Operators
 

Example     Name     Result
$a & $b     And     Bits that are set in both $a and $b are set.
$a | $b     Or (inclusive or)     Bits that are set in either $a or $b are set.
$a ^ $b     Xor (exclusive or)     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")
$a >> $b     Shift right     Shift the bits of $a $b steps to the right (each step means "divide by two")
