BigInteger.Equality Operator (UInt64, BigInteger)

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

This API is not CLS-compliant. 

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

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

Parameters

left
Type: System.UInt64
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(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...
}


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