BigInteger.Division Operator (BigInteger, BigInteger)

 
equivalentCodeEntityM:System.Numerics.BigInteger.Divide(System.Numerics.BigInteger,System.Numerics.BigInteger)

Divides a specified BigInteger value by another specified BigInteger value by using integer division.

Namespace:   System.Numerics
Assembly:  System.Numerics (in System.Numerics.dll)

public static BigInteger operator /(
	BigInteger dividend,
	BigInteger divisor
)

Parameters

dividend
Type: System.Numerics.BigInteger

The value to be divided.

divisor
Type: System.Numerics.BigInteger

The value to divide by.

Return Value

Type: System.Numerics.BigInteger

The integral result of the division.

Exception Condition
DivideByZeroException

divisor is 0 (zero).

The Division method defines the division operation for BigInteger values. It enables code such as the following:

BigInteger num1 = 100045632194;
BigInteger num2 = 90329434;
BigInteger quotient = num1 / num2;

Languages that do not support custom operators and operator overloading can call the Divide method instead.

The following example creates an array of BigInteger values. It then uses each element as the quotient in a division operation that uses the Divide method, the division operator (/), and the DivRem method.

using System.Numerics;

public class Example
{
   public static void Main()
   {
      BigInteger divisor = BigInteger.Pow(Int64.MaxValue, 2);

      BigInteger[] dividends = { BigInteger.Multiply((BigInteger) Single.MaxValue, 2), 
                                 BigInteger.Parse("90612345123875509091827560007100099"), 
                                 BigInteger.One, 
                                 BigInteger.Multiply(Int32.MaxValue, Int64.MaxValue),
                                 divisor + BigInteger.One };

      // Divide each dividend by divisor in three different ways.
      foreach (BigInteger dividend in dividends)
      {
         BigInteger quotient;
         BigInteger remainder = 0;

         Console.WriteLine("Dividend: {0:N0}", dividend);
         Console.WriteLine("Divisor:  {0:N0}", divisor);
         Console.WriteLine("Results:");
         Console.WriteLine("   Using Divide method:     {0:N0}", 
                           BigInteger.Divide(dividend, divisor));
         Console.WriteLine("   Using Division operator: {0:N0}", 
                           dividend / divisor);
         quotient = BigInteger.DivRem(dividend, divisor, out remainder);
         Console.WriteLine("   Using DivRem method:     {0:N0}, remainder {1:N0}", 
                           quotient, remainder);

         Console.WriteLine();
