    using System;

            //Proof that using Single(float), or Double(double) is bad for money calculations.

            double x = 0.1;

            double y = x + x + x;

            Console.WriteLine( y == 0.3 ); // Prints False

            Console.WriteLine( Math.Abs( y - 0.3 ) < double.Epsilon ); // Prints False
