Operators

Bitwise

& Bitwise AND. Copies bit when it exists in both

  • perands.

| Bitwise OR. Copies bit when it exists in either

  • perand.

ˆ Bitwise XOR. Copies the bit if set in one operand, but not both. ∼ Flips the bits. << Binary Left Shift. Left operands value is moved left by right number of bits. >> Binary Right Shift. Left operands value is moved right by right number of bits.
