BigInteger.Equality Operator (Int64, BigInteger)

Microsoft Silverlight will reach end of support after October 2021. Learn more.

Returns a value that indicates whether a signed long integer value and a BigInteger value are equal.

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

Syntax

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

public static bool operator ==(
    long left,
    BigInteger right
)

Type: System.Boolean
true if the left and right parameters have the same value; otherwise, false.

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

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

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

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.

Supported in: 5, 4
