BigInteger.Equality Operator (Int64, BigInteger)

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)

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

Parameters

left
Type: System.Int64
The first value to compare.
right
Type: System.Numerics.BigInteger
The second value to compare.

Return Value

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:


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.
