BigInteger.LessThanOrEqual Operator (UInt64, BigInteger)

 
equivalentCodeEntityM:System.Numerics.BigInteger.CompareTo(System.UInt64)

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)

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.

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 (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 = BigInteger.Parse("9801324316220166912")
If BigInteger.op_LessThanOrEqual(UInt64.MaxValue, number) Then
   ' Do something.
Else
   ' Do something else.
End If
