using System;
public class MainClass
{
    public static void Main(String[] argv)
    {
        float zero = 0.0F;
        // This will return true. 
        if (Single.IsNaN(0 / zero))
        {
            Console.WriteLine("Single.IsNan() can determine whether a value is not-a-number.");
        }

    }
}
