Public Shared Operator >> (value As BigInteger, shift As Integer) As BigInteger

매개 변수

value
BigInteger

비트를 이동할 값입니다.

shift
Int32

value를 오른쪽으로 이동할 비트 수입니다.

반환

BigInteger

지정된 비트 수만큼 오른쪽으로 이동한 값입니다.

구현

RightShift(TSelf, TOther)

설명

메서드는 RightShift 값에 대한 비트 오른쪽 시프트 연산자의 연산을 BigInteger 정의합니다. 다음과 같은 코드를 사용하도록 설정합니다.

var number = BigInteger.Parse("-9047321678449816249999312055");
Console.WriteLine("Shifting {0} right by:", number);
for (int ctr = 0; ctr <= 16; ctr++) {
   BigInteger newNumber = number >> ctr;
   Console.WriteLine(" {0,2} bits: {1,35} {2,30}", ctr, newNumber, newNumber.ToString("X"));
}
