Example

The following code shows how to use Double.Epsilon field.


/*from  w ww . j av a  2  s  . c o m*/
using System;

public class Example
{
   public static void Main()
   {
      double[] values = { 0, Double.Epsilon, Double.Epsilon * .5 };

      for (int ctr = 0; ctr <= values.Length - 2; ctr++)
      {
         for (int ctr2 = ctr + 1; ctr2 <= values.Length - 1; ctr2++)
         {
            Console.WriteLine("{0:r} = {1:r}: {2}", 
                              values[ctr], values[ctr2],  
                              values[ctr].Equals(values[ctr2]));
         }

      }      
   }
}

The code above generates the following result.
