Question

Again i come back with one of my problems and queries.

 using System;
 using System.Collections.Generic;
 using System.Linq;
 using System.Text;

namespace compare_string
   {
     class Program
     {
        static void Main(string[] args)
        {
            string str1 = "85.8500000000000";
            string str2 = "85.85";
            double num1 = Convert.ToDouble(str1);
            double num2 = Convert.ToDouble(str2);
            if (num1 != num2)
            {
                 Console.WriteLine("Unequal");
            }
            else {
                 Console.WriteLine("Equal");
            }
             Console.ReadKey();
         }
    }
  }

Why is give that the two numbers are unequal? Thanks in advance!

Answer 1

This is most probably related with your locale.
Try this, it should work

double num1 = Convert.ToDouble(str1,CultureInfo.InvariantCulture);
double num2 = Convert.ToDouble(str2,CultureInfo.InvariantCulture);

Alo try printing your numbers, you will see the difference.
