BigInteger.CompareTo Method (Int64)

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

Compares this instance to a signed 64-bit integer and returns an integer that indicates whether the value of this instance is less than, equal to, or greater than the value of the signed 64-bit integer.

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

Syntax

'Declaration
Public Function CompareTo ( _
    other As Long _
) As Integer
public int CompareTo(
    long other
)

Parameters

  • other
    Type: System.Int64
    The signed 64-bit integer to compare.

Return Value

Type: System.Int32
A signed integer value that indicates the relationship of this instance to other, as shown in the following table.

Return value

Description

Less than zero

The current instance is less than other.

Zero

The current instance equals other.

Greater than zero

The current instance is greater than other.

Remarks

If other is a Byte, Int16, Int32, SByte, UInt16, or UInt32 value, it is implicitly converted to an Int64 value when the CompareTo(Int64) method is called.

Examples

The following example illustrates the result of calling the CompareTo(Int64) method with integral values.

Dim bigIntValue As BigInteger = 3221123045552

Dim byteValue As Byte = 16
Dim sbyteValue As SByte = -16
Dim shortValue As Short = 1233
Dim ushortValue As UShort = 1233
Dim intValue As Integer = -12233
Dim uintValue As UInteger = 12233
Dim longValue As Long = 12382222
Dim ulongValue As Integer = 1238222
