Solidity: What does the caret ^ operator do?

I searched solidity documentation and there's nothing on this:

What does the caret ^ operator do?

What is it doing here?

sha3(sha3(valueA) ^ sha3(valueB))
Solution

  • The keyword I left out is "bitwise" (as Nathan mentioned).

    So, if, for example,               sha3(valueA)=0x44=0b01000100, and
                                   sha3(valueB)=0x34=0b00110100, then:
(sha3(valueA)=0x44=0b01000100 and sha3(valueB))=0x70=0b01110000

    PS fun fact: XOR with all 1s is a "bit flip"
