BigInteger.Max Method (BigInteger, BigInteger)


The .NET API Reference documentation has a new home. Visit the .NET API Browser on to see the new experience.

Returns the larger of two BigInteger values.

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

public static BigInteger Max(
	BigInteger left,
	BigInteger right


Type: System.Numerics.BigInteger

The first value to compare.

Type: System.Numerics.BigInteger

The second value to compare.

Return Value

Type: System.Numerics.BigInteger

The left or right parameter, whichever is larger.

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

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

using System;
using System.Numerics;

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

      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);
// The example displays the following output:
//       The values:
//                                    -9,223,372,036,854,775,807
//                                                            -1
//                                            10,359,321,239,000
//                                                10,813,504,144
//                                            70,366,596,661,249
//            85,070,591,730,234,615,852,008,593,798,364,921,858
//       The largest number of the series is:
//          85,070,591,730,234,615,852,008,593,798,364,921,858
