Examples

The following example compares the approximate distance of several stars from Earth with the distance of Epsilon Indi from Earth to determine whether they are equal. The example uses each overload of the Equals method to test for equality.

Remarks

To determine the relationship between the two objects instead of just testing for equality, call the BigInteger.CompareTo(UInt64) method.

Applies to

Equals(Object)

Source:: BigInteger.cs

Source:: BigInteger.cs

Source:: BigInteger.cs

Returns a value that indicates whether the current instance and a specified object have the same value.

public:
 override bool Equals(System::Object ^ obj);

public override bool Equals (object obj);

public override bool Equals (object? obj);

override this.Equals : obj -> bool

Public Overrides Function Equals (obj As Object) As Boolean

Parameters

obj: Object

The object to compare.

Returns

Boolean

true if the obj argument is a BigInteger object, and its value is equal to the value of the current BigInteger instance; otherwise, false.

Examples

The following example defines parallel Object and BigInteger arrays. Each element of one array has the same value as the corresponding element of the second array. As the output from the example shows, the instance in the BigInteger array is considered to be equal to the instance in the Object array only if the latter is a BigInteger and their values are equal.

using System;
using System.Numerics;

public class Example
{
   public static void Main()
   {
      object[] obj = { 0, 10, 100, new BigInteger(1000), -10 };
      BigInteger[] bi = { BigInteger.Zero, new BigInteger(10),
                          new BigInteger(100), new BigInteger(1000),
                          new BigInteger(-10) };
      for (int ctr = 0; ctr < bi.Length; ctr++)
         Console.WriteLine(bi[ctr].Equals(obj[ctr]));
   }
}
// The example displays the following output:
//       False
//       False
//       False
//       True
//       False

open System.Numerics

let obj: obj[] = [| 0; 10; 100; BigInteger 1000; -10 |]

let bi =
    [| BigInteger.Zero
       BigInteger 10
       BigInteger 100
       BigInteger 1000
       BigInteger -10 |]

for ctr = 0 to bi.Length - 1 do
    printfn $"{bi.[ctr].Equals(obj.[ctr])}"
// The example displays the following output:
//       False
//       False
//       False
//       True
//       False

Imports System.Numerics

Module Example
   Public Sub Main()
      Dim obj() As object = { 0, 10, 100, New BigInteger(1000), -10 }
      Dim bi() As BigInteger = { BigInteger.Zero, New BigInteger(10),
                                 New BigInteger(100), New BigInteger(1000),
                                 New BigInteger(-10) }
      For ctr As Integer = 0 To bi.Length - 1
         Console.WriteLine(bi(ctr).Equals(obj(ctr)))
      Next                           
   End Sub
End Module
' The example displays the following output:
'       False
'       False
'       False
'       True
'       False

Remarks

If the obj argument is not a BigInteger value, the method returns false. The method returns true only if obj is a BigInteger instance whose value is equal to the current instance.

To determine the relationship between the two objects instead of just testing for equality, call the CompareTo(Object) method.

Applies to

Equals(BigInteger)

Source:: BigInteger.cs

Source:: BigInteger.cs

Remarks

This method implements the IEquatable<T> interface and performs slightly better than Equals(Object) because it does not have to convert the other parameter to a BigInteger object.

To determine the relationship between the two BigInteger objects instead of just testing for equality, call the BigInteger.CompareTo(BigInteger) method.

Applies to

Equals(Int64)

Source:: BigInteger.cs

Source:: BigInteger.cs

Source:: BigInteger.cs

Returns a value that indicates whether the current instance and a signed 64-bit integer have the same value.

public:
 bool Equals(long other);

public bool Equals (long other);

override this.Equals : int64 -> bool

Public Function Equals (other As Long) As Boolean

Parameters

other: Int64

The signed 64-bit integer value to compare.

Returns

Boolean

true if the signed 64-bit integer and the current instance have the same value; otherwise, false.

Examples

The following example instantiates a BigInteger object from each integral type except UInt64. It then calls the Equals(Int64) method to compare the BigInteger value with the original integer value that was passed to the BigInteger constructor. As the output shows, the values are equal in each case.

Remarks

If other is a Byte, Int16, Int32, SByte, UInt16, or UInt32 value, it is implicitly converted to an Int64 value when the method is called.

To determine the relationship between the two objects instead of just testing for equality, call the BigInteger.CompareTo(Int64) method.
