설명

합니다 LeftShift 메서드 정의 작업에 대 한 비트 왼쪽 시프트 연산자의 BigInteger 값입니다.The LeftShift method defines the operation of the bitwise left-shift operator for BigInteger values. 다음과 같은 코드 수 있도록 합니다.It enables code such as the following:

BigInteger number = BigInteger.Parse("-9047321678449816249999312055");
Console.WriteLine("Shifting {0} left 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"));
}

참고

정수 기본 요소를 사용 하 여 비트 왼쪽 시프트 작업과 달리 합니다 LeftShift 메서드는 원래의 부호를 유지 BigInteger 값입니다.Unlike the bitwise left-shift operation with integer primitives, the LeftShift method preserves the sign of the original BigInteger value.

사용자 지정 연산자를 지원 하지 않는 언어와 왼쪽 시프트 연산을 수행할 수 valueBigInteger.Pow(2, shift)입니다.Languages that do not support custom operators can perform a bitwise left-shift operation by multiplying value by BigInteger.Pow(2, shift). 다음 예제에서는 결과 동일한이 연산자를 사용 하 여 결과에 표시 됩니다.The following example shows that the results are identical to the results of using this operator.

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