using System;
using System.Collections;
public class Tuple1Comparer : IEqualityComparer
{
new public bool Equals(object x, object y)
{
// Check if x is a floating point type. If x is, then y is.
if (x is double | x is float)
{
// Convert to Double values.
double dblX = (double) x;
double dblY = (double) y;
if (Double.IsNaN(dblX) | Double.IsInfinity(dblX) |
Double.IsNaN(dblY) | Double.IsInfinity(dblY))
return dblX.Equals(dblY);
else
return Math.Abs(dblX - dblY) <= dblX * .0001;
}
else
{
return x.Equals(y);
