Parameters

Retouren

De bitwise one's complement van value.

Opmerkingen

De OnesComplement methode definieert de werking van de bitsgewijze complementoperator voor BigInteger waarden. De bitsgewijze complementoperator draait elke bit om in een numerieke waarde. Dat wil gezegd, bits die value 0 zijn ingesteld op 1 in het resultaat en bits die 1 zijn ingesteld op 0 in het resultaat. De OnesComplement methode schakelt code in, zoals de volgende:

using System;
using System.Numerics;

public class Example
{
   public static void Main()
   {
      BigInteger value, complement;

      value = BigInteger.Multiply(BigInteger.One, 9);
      complement = ~value;

      Console.WriteLine("{0,5} -- {1,-32}", value, DisplayInBinary(value));
      Console.WriteLine("{0,5} -- {1,-32}\n", complement, DisplayInBinary(complement));

      value = BigInteger.MinusOne * SByte.MaxValue;
      complement = ~value;

      Console.WriteLine("{0,5} -- {1,-32}", value, DisplayInBinary(value));
      Console.WriteLine("{0,5} -- {1,-32}\n", complement, DisplayInBinary(complement));
   }

   private static string DisplayInBinary(BigInteger number)
   {
      byte[] bytes = number.ToByteArray();
      string binaryString = string.Empty;
      foreach (byte byteValue in bytes)
      {
         string byteString = Convert.ToString(byteValue, 2).Trim();
         binaryString += byteString.Insert(0, new string('0', 8 - byteString.Length));
      }
      return binaryString;
   }
}
// The example displays the following output:
//           9 -- 00001001
//         -10 -- 11110110

//        -127 -- 10000001
//         126 -- 01111110

Talen die geen ondersteuning bieden voor aangepaste operators, kunnen de OnesComplement methode mogelijk rechtstreeks aanroepen om een bitsgewijze aanvullingsbewerking uit te voeren. Voorbeeld:

Imports System.Numerics

      Dim value, complement As bigInteger
