BigInteger.Equality Operator

Definition

Returns a value that indicates whether two values are equal.

Overloads

Equality(UInt64, BigInteger)

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

Equality(BigInteger, BigInteger)

Returns a value that indicates whether the values of two BigInteger objects are equal.

Equality(BigInteger, UInt64)

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

Equality(Int64, BigInteger)

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

Equality(BigInteger, Int64)

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

Important

This API is not CLS-compliant.

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

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

Parameters

left
UInt64

The first value to compare.

right
BigInteger

The second value to compare.

Returns

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

Attributes

Remarks

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

C#
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.

Equality(BigInteger, BigInteger)

Source:
BigInteger.cs
Source:
BigInteger.cs
Source:
BigInteger.cs

Returns a value that indicates whether the values of two BigInteger objects are equal.

C#
public static bool operator ==(System.Numerics.BigInteger left, System.Numerics.BigInteger right);

Parameters

left
BigInteger

The first value to compare.

right
BigInteger

The second value to compare.

Returns

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

Remarks

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

C#
BigInteger number1 = 945834723;
BigInteger number2 = 345145625;
BigInteger number3 = 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).

Equality(Int64, BigInteger)

Source:
BigInteger.cs
Source:
BigInteger.cs
Source:
BigInteger.cs

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

C#
public static bool operator ==(long left, System.Numerics.BigInteger right);

Parameters

left
Int64

The first value to compare.

right
BigInteger

The second value to compare.

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:

C#
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.

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