What is New in the .NET Framework 4-Tips No-01

Introduction

The purpose this structure is an arbitrary-precision integer data type that supports all the standard integer operations, including bit manipulation. It can be used from any .NET Framework language. In addition, some of the new .NET Framework languages (such as F# and IronPython) have built-in support for this structure.

How to use

Declaration

BigInteger objbigInt = new BigInteger(179032.6541);

Another way of declaration,

create a long variable and then assign directly that variable to bigInteger object like followings.

long longValue = 6315489358112;      
BigInteger assignedFromLong = longValue;

And this is also support all type of basic casting and convert as hexa.

Complete Sample

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Numerics;
namespace ConsoleApplication1
{
    class Program
    {
        static void Main(string[] args)
        {
            string positiveNoString = "91389681247993671255432112000000";
            string negativeNoString = "-90315837410896312071002088037140000";
            BigInteger posBigInt = 0;
            BigInteger negBigInt = 0;

            try
            {
                posBigInt = BigInteger.Parse(positiveNoString);
                Console.WriteLine(posBigInt);
            }
            catch (FormatException)
            {
                Console.WriteLine("Unable to convert the string '{0}' to a BigInteger value.",
                                  positiveNoString);
            }

            if (BigInteger.TryParse(negativeNoString, out negBigInt))
                Console.WriteLine(negBigInt);
            else
                Console.WriteLine("Unable to convert the string '{0}' to a BigInteger value.",
                                   negativeNoString);
  
       
        }
    }
}
