# BigInteger.LessThanOrEqual Operator

## Definition

Returns a value that indicates whether a specified value is less than or equal to another specified value.

 LessThanOrEqual(Int64, BigInteger) Returns a value that indicates whether a 64-bit signed integer is less than or equal to a BigInteger value. LessThanOrEqual(BigInteger, Int64) Returns a value that indicates whether a BigInteger value is less than or equal to a 64-bit signed integer. LessThanOrEqual(BigInteger, BigInteger) Returns a value that indicates whether a BigInteger value is less than or equal to another BigInteger value. LessThanOrEqual(BigInteger, UInt64) Returns a value that indicates whether a BigInteger value is less than or equal to a 64-bit unsigned integer. LessThanOrEqual(UInt64, BigInteger) Returns a value that indicates whether a 64-bit unsigned integer is less than or equal to a BigInteger value.

## LessThanOrEqual(Int64, BigInteger)

Source:

Source:

Returns a value that indicates whether a 64-bit signed integer is less than or equal to a BigInteger value.

``````public:
static bool operator <=(long left, System::Numerics::BigInteger right);``````
``public static bool operator <= (long left, System.Numerics.BigInteger right);``
``static member ( <= ) : 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

`true` if `left` is less than or equal to `right`; otherwise, `false`.

### Remarks

The LessThanOrEqual method defines the operation of the less than or equal to operator for BigInteger values. It enables code such as the following:

``````BigInteger number = BigInteger.Parse("9801324316220166912");
if (Int64.MaxValue <= number)
{
// Do something.
}
else
{
// Do something else.
}
``````
``````Dim number As BigInteger = BigInteger.Parse("9801324316220166912")
If Int64.MaxValue <= number Then
' Do something.
Else
' Do something else.
End If
``````

Languages that do not support custom operators can call the BigInteger.CompareTo(Int64) method instead. They can also call the LessThanOrEqual(Int64, BigInteger) method directly, as the following example shows.

``````Dim number As BigInteger = BigInteger.Parse("9801324316220166912")
If BigInteger.op_LessThanOrEqual(Int64.MaxValue, number) Then
' Do something.
Else
' Do something else.
End If
``````

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.CompareTo(Int64).

``static member ( <= ) : 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

`true` if `left` is less than or equal to `right`; otherwise, `false`.

### Remarks

The LessThanOrEqual method defines the operation of the less than or equal to operator for BigInteger values. It enables code such as the following:

``````BigInteger number1 = 945834723;
BigInteger number2 = 345145625;
BigInteger number3 = 945834724;
BigInteger number4 = 945834723;
Console.WriteLine(number1 <= number2);             // Displays False
Console.WriteLine(number1 <= number3);             // Displays True
Console.WriteLine(number1 <= number4);             // Displays True

``````Dim number1 As BigInteger = 945834723
Dim number2 As BigInteger = 345145625
Dim number3 As BigInteger = 945834724
Dim number4 As BigInteger = 945834723
Console.WriteLine(number1 <= number2)                 ' Displays False

Languages that do not support custom operators can call the Compare method instead. They can also call the LessThanOrEqual(BigInteger, BigInteger) method directly, as the following example shows.

``````Dim numberA As BigInteger = 945834723
Dim numberB As BigInteger = 345145625
Dim numberC As BigInteger = 945834724
Dim numberD As BigInteger = 945834723
Console.WriteLine( _
BigInteger.op_LessThanOrEqual(numberA, numberB))    ' Displays False
Console.WriteLine( _
BigInteger.op_LessThanOrEqual(numberA, numberC))    ' Displays True
Console.WriteLine( _
BigInteger.op_LessThanOrEqual(numberA, numberD))    ' Displays True

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