BigInteger.Max(BigInteger, BigInteger) Method

Definition

Namespace:

System.Numerics

Assembly:

System.Runtime.Numerics.dll

Source:

BigInteger.cs

Returns the larger of two BigInteger values.

public:
 static System::Numerics::BigInteger Max(System::Numerics::BigInteger left, System::Numerics::BigInteger right) = System::Numerics::INumber<System::Numerics::BigInteger>::Max;

public static System.Numerics.BigInteger Max (System.Numerics.BigInteger left, System.Numerics.BigInteger right);

static member Max : System.Numerics.BigInteger * System.Numerics.BigInteger -> System.Numerics.BigInteger

Public Shared Function Max (left As BigInteger, right As BigInteger) As BigInteger

Parameters

left

BigInteger

The first value to compare.

right

BigInteger

The second value to compare.

Returns

BigInteger

The left or right parameter, whichever is larger.

Implements

Max(TSelf, TSelf)

Examples

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