WebNov 14, 2024 · The " =" operator actually adds a flag to the enum, so the enum now contains two flag bits. You can use " =" to add bits, while & will test bits without setting them. And Bitwise AND returns a value with 1 in the targeted bit if both values contain the bit. And Tip You can therefore AND two values together and test the result for the target bit.
