using System.Globalization;
using System.Windows.Data;

namespace YourNamespace
{
    public class DoubleToStringConverter : IValueConverter
    {
        public object Convert(object value, Type targetType, object parameter, CultureInfo culture)
        {
            if (value is double)
            {
                double number = (double)value;
                if (double.IsPositiveInfinity(number))
                {
                    return "Infinity";
                }
            }
            return value.ToString();
        }
