BigInteger.Max(BigInteger, BigInteger) 方法

定義

命名空間:

System.Numerics

組件:

netstandard.dll, System.Runtime.Numerics.dll

來源:

BigInteger.cs

回傳兩個 BigInteger 值中較大的那個。

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

第一個要比較的值。

right

BigInteger

要比較的第二個值。

傳回

BigInteger

或leftright參數，以較大者為準。

實作

Max(TSelf, TSelf)

範例

以下範例使用此 Max 方法來選擇數值陣列 BigInteger 中最大的數字。

using System.Numerics;
