XNOR Operator

NOT Exclusive OR. In binary logic, XNOR (NOT EXCLUSIVE OR) is represented as the operator with the following results for binary operations:

0 XNOR 0 = 1
0 XNOR 1 = 0
1 XNOR 0 = 0
1 XNOR 1 = 1

The results are the opposite of those for the operator XOR. When both binary input values are 0 or 1, then the result is 1. Otherwise, the result is 0. Used in logic gates for computers, 0 is false, 1 is true. Despite the arrangement of the letters in XNOR, it represents not-exclusive-or, rather than exclusive-not-or. In the mathematics of Boolean algebra, used to manipulate Boolean equations, these operators have special symbols.
