Bitwise operators

     

Operator                Description
&                       The bitwise AND operator that compares bits and returns 1 when each bit equals 1. Otherwise, 0 is returned.
|                       The bitwise OR operator that compares bits and returns 1 when at least one of the bits equals 1. Otherwise, 0 is returned.
^                       The bitwise XOR operator that compares bits and returns 1 if exactly one of the bits equals 1. Otherwise, 0 is returned.
~                       The bitwise negation operator that inverts all bits in a specified number. All 0 bits are converted to 1, and all 1 bits are converted to 0.
<<                      The bitwise shift left operator that shifts all bits to the left by the specified number of positions.
>>                      The bitwise shift right operator that shifts all bits to the right by the specified number of positions.
