BigInteger.Max Method

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

Returns the larger of two BigInteger values.

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

Syntax

'Declaration
Public Shared Function Max ( _
    left As BigInteger, _
    right As BigInteger _
) As BigInteger

public static BigInteger Max(
    BigInteger left,
    BigInteger right
)

Parameters

left
Type: System.Numerics.BigInteger
The first value to compare.

right
Type: System.Numerics.BigInteger
The second value to compare.

Return Value

Type: System.Numerics.BigInteger
The left or right parameter, whichever is larger.

Remarks

This method corresponds to the Math.Max method for primitive numeric types.

Examples

The following example uses the Max method to select the largest number in an array of BigInteger values.
