Açıklamalar

RightShift yöntemi, değerler için BigInteger bit düzeyinde right-shift işlecinin işlemini tanımlar. Bu, aşağıdaki gibi bir kod sağlar:

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"));
}

Özel işleçleri desteklemeyen diller, negatif değerler için 1 kez shift bölerek valueBigInteger.Pow(2, shift) ve çıkararak bit tabanlı bir sağa kaydırma işlemi gerçekleştirebilir. Aşağıdaki örnek, sonuçların bu işleci kullanmanın sonuçlarıyla aynı olduğunu gösterir.

var number = BigInteger.Parse("-9047321678449816249999312055");
Console.WriteLine("Shifting {0} right by:", number);
for (int ctr = 0; ctr <= 16; ctr++) {
   BigInteger newNumber = BigInteger.Divide(number, BigInteger.Pow(2, ctr));
   if (newNumber * ctr < 0)
      newNumber--;

   Console.WriteLine(" {0,2} bits: {1,35} {2,30}",
                     ctr, newNumber, newNumber.ToString("X"));
