Try to calculate machine epsilon

Main.cs

using System;

namespace MachineEpsilon
{
	class MainClass
	{
		public static void Main (string[] args)
		{
			double machEps = 1.0d;
			
			do {
				machEps /= 2.0d;
			}
			while ((double)(1.0 + machEps) != 1.0);
			
			Console.WriteLine( "Calculated machine epsilon: " + machEps );
		}
	}
}
