BigInteger.LessThanOrEqual Operator (UInt64, BigInteger)

Microsoft Silverlight will reach end of support after October 2021. Learn more.

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

This API is not CLS-compliant.

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

Syntax

'Declaration
Public Shared Operator <= ( _
    left As ULong, _
    right As BigInteger _
) As Boolean

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 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:

Dim number As BigInteger = 9801324316220166912ul
If UInt64.MaxValue <= number Then
   ' Do something.
Else
   ' Do something else.
End If

BigInteger number = 9801324316220166912;
if (UInt64.MaxValue <= number)
{
   // Do something.
}
else
{
   // Do something else.
}

Languages that do not support custom operators can call the BigInteger.CompareTo(UInt64) method instead. They can also call the LessThanOrEqual(UInt64, BigInteger) method directly, as the following example shows.

Dim number As BigInteger = 9801324316220166912ul
If BigInteger.op_LessThanOrEqual(UInt64.MaxValue, number) Then
   ' Do something.
Else
   ' Do something else.
End If
