 static bool operator ==(System::UInt64 left, System::Numerics::BigInteger right);

[System.CLSCompliant(false)]
public static bool operator ==(ulong left, System.Numerics.BigInteger right);

[<System.CLSCompliant(false)>]
static member ( = ) : uint64 * System.Numerics.BigInteger -> bool

Public Shared Operator == (left As ULong, right As BigInteger) As Boolean

Parameters

Returns

true if the left and right parameters have the same value; otherwise, false.

Attributes

CLSCompliantAttribute

Remarks

The Equality(UInt64, BigInteger) method defines the equality comparison operation for BigInteger values. It enables code such as the following:

BigInteger bigNumber = BigInteger.Pow(2, 63) - BigInteger.One;
ulong uNumber = Int64.MaxValue & 0x7FFFFFFFFFFFFFFF;
if (uNumber == bigNumber)
{
   // Do something...
}

let bigNumber = BigInteger.Pow(2, 63) - BigInteger.One
let uNumber = uint64 Int64.MaxValue &&& 0x7FFFFFFFFFFFFFFFuL

if bigint uNumber = bigNumber then
    // Do something...

Dim bigNumber As BigInteger = BigInteger.Pow(2, 63) - BigInteger.One
Dim uNumber As ULong = CULng(Int64.MaxValue And CULng(&h7FFFFFFFFFFFFFFF))
If uNumber = bigNumber Then
   ' Do something...
End If

Languages that do not support custom operators can call the BigInteger.Equals(UInt64) instance method instead.

Remarks

The Equality(BigInteger, BigInteger) method defines the operation of the equality operator for BigInteger values. It enables code such as the following:

BigInteger number1 = 945834723;
BigInteger number2 = 345145625;
BigInteger number3 = 945834723;
Console.WriteLine(number1 == number2);             // Displays False
Console.WriteLine(number1 == number3);             // Displays True

let number1 = 945834723I
let number2 = 345145625I
let number3 = 945834723I
printfn $"{number1 = number2}" // Displays False
printfn $"{number1 = number3}" // Displays True

Dim number1 As BigInteger = 945834723
Dim number2 As BigInteger = 345145625
Dim number3 As BigInteger = 945834723 
Console.WriteLine(number1 = number2)                  ' Displays False
Console.WriteLine(number1 = number3)                  ' Displays True

Languages that do not support custom operators can call the BigInteger.Equals(BigInteger) instance method instead.

The equivalent method for this operator is BigInteger.Equals(BigInteger).

Remarks

The Equality(BigInteger, UInt64) method defines the equality comparison operation for BigInteger values. It enables code such as the following:

BigInteger bigNumber = BigInteger.Pow(2, 63) - BigInteger.One;
ulong uNumber = Int64.MaxValue & 0x7FFFFFFFFFFFFFFF;
if (bigNumber == uNumber)
{
   // Do something...
}

let bigNumber = BigInteger.Pow(2, 63) - BigInteger.One
let uNumber = uint64 Int64.MaxValue &&& 0x7FFFFFFFFFFFFFFFuL

if bigNumber = uNumber then
    // Do something...

Dim bigNumber As BigInteger = BigInteger.Pow(2, 63) - BigInteger.One
Dim uNumber As ULong = CULng(Int64.MaxValue And CULng(&h7FFFFFFFFFFFFFFF))
If bigNumber = uNumber Then
   ' Do something...
End If

Languages that do not support custom operators can call the BigInteger.Equals(UInt64) instance method instead.

static member ( = ) : int64 * System.Numerics.BigInteger -> bool

Public Shared Operator == (left As Long, right As BigInteger) As Boolean

Parameters

Returns

true if the left and right parameters have the same value; otherwise, false.

Remarks

The Equality(Int64, BigInteger) method defines the equality comparison operation for BigInteger values. It enables code such as the following:

BigInteger bigNumber = BigInteger.Pow(2, 63);
long number = Int64.MaxValue;
if (number == bigNumber)
{
   // Do something...
}

let bigNumber = BigInteger.Pow(2, 63)
let number = Int64.MaxValue

if bigint number = bigNumber then
    // Do something...

Dim bigNumber As BigInteger = BigInteger.Pow(2, 63)
Dim number As Long = Int64.MaxValue
If number = bigNumber Then
   ' Do something...
End If

Languages that do not support custom operators can call the BigInteger.Equals(Int64) instance method instead.

If left is a Byte, Int16, Int32, SByte, UInt16, or UInt32 value, it is implicitly converted to an Int64 value when the operation is performed.

The equivalent method for this operator is BigInteger.Equals(Int64).
