WebSep 15, 2024 · Bitwise operations evaluate two integral values in binary (base 2) form. They compare the bits at corresponding positions and then assign values based on the comparison. The following example illustrates the And operator. VB Dim x As Integer x = 3 And 5 The preceding example sets the value of x to 1. This happens for the following … 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.
