WebJan 24, 2024 · The bitwise NOT operator (~) is perhaps the easiest to understand of all the bitwise operators. It simply flips each bit from a 0 to a 1, or vice versa. Note that the result of a bitwise NOT is dependent on what size your data type is. Flipping 4 bits: ~0100 is 1011. Flipping 8 bits: ~0000 0100 is 1111 1011.
