BigInteger.Max(BigInteger, BigInteger) 方法

定义

命名空间:

System.Numerics

程序集:

System.Runtime.Numerics.dll

Source:

BigInteger.cs

返回两个 BigInteger 值中的较大者。

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

参数

left

BigInteger

要比较的第一个值。

right

BigInteger

要比较的第二个值。

返回

BigInteger

left 或 right 参数中较大的一个。

实现

Max(TSelf, TSelf)

示例

以下示例使用 Max 方法选择值数组 BigInteger 中的最大数字。

using System;
using System.Numerics;

   public static void Main()
   {
      BigInteger[] numbers = { Int64.MaxValue * BigInteger.MinusOne,
                               BigInteger.MinusOne,

                               BigInteger.Pow(103988, 2),
                               BigInteger.Multiply(Int32.MaxValue, Int16.MaxValue),
                               BigInteger.Add(BigInteger.Pow(Int64.MaxValue, 2),
                               BigInteger.Pow(Int32.MaxValue, 2)) };
      if (numbers.Length < 2)
      {
         Console.WriteLine("Cannot determine which is the larger of {0} numbers.",
                            numbers.Length);
         return;
      }

      BigInteger largest = numbers[numbers.GetLowerBound(0)];

      for (int ctr = numbers.GetLowerBound(0) + 1; ctr <= numbers.GetUpperBound(0); ctr++)
         largest = BigInteger.Max(largest, numbers[ctr]);

      Console.WriteLine("The values:");
      foreach (BigInteger number in numbers)
         Console.WriteLine("{0,55:N0}", number);

      Console.WriteLine("\nThe largest number of the series is:");
      Console.WriteLine("   {0:N0}", largest);
   }
}
