Exclusive Or Operator

<exclusive-or-operator>

^

^

name: Exclusive OR (bitwise XOR)
side effect: None.
associativity: Left to right.   (The bitwise XOR operation is associative.)
commutativity: The bitwise XOR operation is commutative.
note: The Bitwise XOR operation does not short circuit.

^ (^: int × int → int)

operand types: int
result value: Each bit of the result is the boolean XOR of the corresponding bits of the operors.
result type: int
note: Operands of byte and short type are cast to int type.

• For each bit position of numeric operands, the result is 0 iff both operands are the same.
• For each bit position of numeric operands, the result is 1 iff the operands are different.

• The exclusive or operator is not defined for real operands.
