C#-ビット演算子
次の表に、C#でサポートされているビット演算子を示します。 変数Aが60を保持し、変数Bが13を保持すると仮定します-
Operator | Description | Example |
---|---|---|
& | Binary AND Operator copies a bit to the result if it exists in both operands. | (A & B) = 12, which is 0000 1100 |
Binary OR Operator copies a bit if it exists in either operand. | ||
(A | B) = 61, which is 0011 1101 | ^ |
Binary XOR Operator copies the bit if it is set in one operand but not both. | (A ^ B) = 49, which is 0011 0001 | ~ |
Binary Ones Complement Operator is unary and has the effect of 'flipping' bits. | (~A ) = -61, which is 1100 0011 in 2’s complement due to a signed binary number. | << |
Binary Left Shift Operator. The left operands value is moved left by the number of bits specified by the right operand. | A << 2 = 240, which is 1111 0000 | >> |
