BigIntegerExtender

BigIntegerExtender is written in C# and extends System.Numerics.BigInteger to support serialization and the calculation of square roots. It contains:

• BigIntegerSerializable: this enables you to serialize System.Numerics.BigInteger objects.
• BigIntegerExtender: it has an extension method that adds the function Sqrt to System.Numerics.BigInteger objects.

Examples

Remember to add System.Numerics.BigInteger, BigIntegerExtender and System.Xml before using this library in your projects.

using System;
using System.Numerics;

namespace Example1
{
    class Program
    {
        static void Main(string[] args)
        {
            while (true)
            {
                BigInteger value;
                do
                {
                    Console.Write("Enter a valid number: ");
                } while (!BigInteger.TryParse(Console.ReadLine(), out value));

                try
                {
                    BigInteger sqrt = value.Sqrt();
                    Console.WriteLine(String.Format("Sqrt of {0}: {1}\n", value, sqrt));
                }
                catch(ArithmeticException)
                {
                    Console.WriteLine(String.Format("Sqrt of {0}: NaN\n", value));
                }
            }
        }
    }
}

using System;
using System.Numerics;
using System.Xml.Serialization;

namespace Example2
{
    class Program
    {
        static void Main(string[] args)
        {
            while (true)
            {
                BigInteger value;
                do
                {
                    Console.Write("Enter a valid number: ");
                } while (!BigInteger.TryParse(Console.ReadLine(), out value));

                var ms = new System.IO.MemoryStream();
                var serializer = new XmlSerializer(typeof(BigIntegerSerializable));
                serializer.Serialize(ms, (BigIntegerSerializable)value);

                Console.Write("\nXML: ");
                Console.WriteLine(System.Text.Encoding.UTF8.GetString(ms.ToArray()));
                Console.WriteLine("\n");
            }
        }
    }
}
