# BigInteger.Inequality Operator

## Definition

Returns a value that indicates whether two numeric values are not equal.

 Inequality(Int64, BigInteger) Returns a value that indicates whether a 64-bit signed integer and a BigInteger value are not equal. Inequality(BigInteger, Int64) Returns a value that indicates whether a BigInteger value and a 64-bit signed integer are not equal. Inequality(BigInteger, BigInteger) Returns a value that indicates whether two BigInteger objects have different values. Inequality(BigInteger, UInt64) Returns a value that indicates whether a BigInteger value and a 64-bit unsigned integer are not equal. Inequality(UInt64, BigInteger) Returns a value that indicates whether a 64-bit unsigned integer and a BigInteger value are not equal.

## Inequality(Int64, BigInteger)

Returns a value that indicates whether a 64-bit signed integer and a BigInteger value are not equal.

``````public:
static bool operator !=(long left, System::Numerics::BigInteger right);``````
``public static bool operator != (long left, System.Numerics.BigInteger right);``
``static member op_Inequality : int64 * System.Numerics.BigInteger -> bool``
``Public Shared Operator != (left As Long, right As BigInteger) As Boolean``

#### Parameters

left
Int64

The first value to compare.

right
BigInteger

The second value to compare.

#### Returns

Boolean

`true` if `left` and `right` are not equal; otherwise, `false`.

### Remarks

The Inequality method defines the operation of the inequality operator 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...
}
``````
``````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 test for inequality by using one of the following techniques:

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.

## Inequality(BigInteger, Int64)

Returns a value that indicates whether a BigInteger value and a 64-bit signed integer are not equal.

``````public:
static bool operator !=(System::Numerics::BigInteger left, long right);``````
``public static bool operator != (System.Numerics.BigInteger left, long right);``
``static member op_Inequality : System.Numerics.BigInteger * int64 -> bool``
``Public Shared Operator != (left As BigInteger, right As Long) As Boolean``

#### Parameters

left
BigInteger

The first value to compare.

right
Int64

The second value to compare.

#### Returns

Boolean

`true` if `left` and `right` are not equal; otherwise, `false`.

### Remarks

The Inequality method defines the operation of the inequality operator for BigInteger values. It enables code such as the following:

``````BigInteger bigNumber = BigInteger.Pow(2, 63);
long number = Int64.MaxValue;
if (bigNumber != number)
{
// Do something...
}
``````
``````Dim bigNumber As BigInteger = BigInteger.Pow(2, 63)
Dim number As Long = Int64.MaxValue
If bigNumber <> number Then
' Do something...
End If
``````

Languages that do not support custom operators can test for inequality by using one of the following techniques:

If `right` 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.CompareTo(Int64).

## Inequality(BigInteger, BigInteger)

Returns a value that indicates whether two BigInteger objects have different values.

``````public:
static bool operator !=(System::Numerics::BigInteger left, System::Numerics::BigInteger right);``````
``public static bool operator != (System.Numerics.BigInteger left, System.Numerics.BigInteger right);``
``static member op_Inequality : System.Numerics.BigInteger * System.Numerics.BigInteger -> bool``
``Public Shared Operator != (left As BigInteger, right As BigInteger) As Boolean``

#### Parameters

left
BigInteger

The first value to compare.

right
BigInteger

The second value to compare.

#### Returns

Boolean

`true` if `left` and `right` are not equal; otherwise, `false`.

### Remarks

The Inequality method defines the operation of the inequality 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 True
Console.WriteLine(number1 != number3);             // Displays False
``````
``````Dim number1 As BigInteger = 945834723
Dim number2 As BigInteger = 345145625
Dim number3 As BigInteger = 945834723
Console.WriteLine(number1 <> number2)                  ' Displays True
Console.WriteLine(number1 <> number3)                  ' Displays False
``````

Languages that do not support custom operators can test for inequality by using one of the following techniques:

The equivalent method for this operator is BigInteger.Compare(BigInteger, BigInteger).
