BigInteger.Max(BigInteger, BigInteger) 方法

定義

傳回兩個 BigInteger 值的較大值。

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

參數

left
BigInteger

要比較的第一個值。

right
BigInteger

要比較的第二個值。

傳回

leftright 參數,擇一較大者。

實作

範例

下列範例會 Max 使用 方法,在值數組 BigInteger 中選取最大數目。

using System;
using System.Numerics;
