result = numeric-expression1 XOR numeric-expression2
■ The logical "exclusive or" operator compares corresponding bits in
numeric-expression1 and numeric-expression2, then sets the corresponding
bit in the result according to the following table:
═══════════════════════ ════════════════════════ ═════════════
Bit in first expression Bit in second expression Bit in result
═══════════════════════ ════════════════════════ ═════════════
1 1 0
