WebBitwise operators vs mathematical operators - You are used to mathematical operators like +, *, / doing math on the numerical value that the binary stored in an int represents - Sometimes we don’t want to think of ints as numerical values, but as groups of bits - Bitwise operators like , &, ^ let us do stuﬀ to the bits stored in an int WebXOR: - Half of the white pixels will be displayed correctly - Half of the black pixels will be displayed correctly So for the AND and OR one of the colors is being displayed correctly and the opposite color looks like noise. For XOR, both of the colors look like noise.
