설명
이 메서드는 LeftShift 값에 대한 비트 왼쪽 시프트 연산자의 연산을 BigInteger 정의합니다. 다음과 같은 코드를 사용할 수 있습니다.
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 형식의 비트 왼쪽 시프트 연산과 달리 메서드는 LeftShift 원래 BigInteger 값의 부호를 유지합니다.
사용자 지정 연산자를 지원하지 않는 언어는 을 곱 value BigInteger.Pow(2, shift)하여 비트 왼쪽 시프트 작업을 수행할 수 있습니다. 다음 예제에서는 결과가 이 연산자를 사용한 결과와 동일하다는 것을 보여줍니다.
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}",
ctr, newNumber, newNumber.ToString("X"));
