Açıklamalar

yöntemi, LeftShift değerler için BigInteger bit düzeyinde sol kaydırma işlecinin işlemini tanımlar. Bu, aşağıdaki gibi bir kod sağlar:

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"));
}

Not

Tamsayı temelleri olan bit düzeyinde sol kaydırma işleminden farklı olarak LeftShift , yöntem özgün BigInteger değerin işaretini korur.

Özel işleçleri desteklemeyen diller ile çarparak valueBigInteger.Pow(2, shift)bit tabanlı bir sola kaydırma işlemi gerçekleştirebilir. Aşağıdaki örnek, sonuçların bu işleci kullanmanın sonuçlarıyla aynı olduğunu gösterir.

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"));
}
