WebWhen using the _Bool type, the compiler clearly exploits that it only has two possible values ( 0 for false and 1 for true), producing a very similar result to the ~a b solution (the only difference being that the latter performs a complement on all bits instead of just the lowest bit). Compiling for 64 bits gives just about the same results. WebJan 24, 2024 · Go provides the following bitwise operators: &: Bitwise AND. : Bitwise OR. ^: Bitwise XOR. &^: Bit clear (AND NOT) <<: Left shift. >>: Right shift.
