An XOR (exclusive OR) logic gate is a digital logic gate that outputs true or high (1) only when the number of true inputs is odd. In the case of a two-input XOR gate, the output is true if either, ...

Yup, xor is not often used in general-purpose software, though it is used in quite a few encryption and hashing algorithms. But that's bitwise-xor. I'm scratching my head trying to come up with a ...
