示例1:
double nan1 = Double.NaN;
Console.WriteLine("{0} + {1} = {2}", 3, nan1, 3 + nan1);
Console.WriteLine("Abs({0}) = {1}", nan1, Math.Abs(nan1));输出：
3 + NaN = NaN Abs(NaN) = NaN
示例2: if
Double zero = 0;
// This condition will return false.
if ((0 / zero) == Double.NaN)
Console.WriteLine("0 / 0 can be tested with Double.NaN.");
else
Console.WriteLine("0 / 0 cannot be tested with Double.NaN; use Double.IsNan() instead.");示例3: Main
//引入命名空间
using System;
public class Example
{
public static void Main()
{
Console.WriteLine("NaN == NaN: {0}", Double.NaN == Double.NaN);
Console.WriteLine("NaN != NaN: {0}", Double.NaN != Double.NaN);
Console.WriteLine("NaN.Equals(NaN): {0}", Double.NaN.Equals(Double.NaN));
Console.WriteLine("! NaN.Equals(NaN): {0}", ! Double.NaN.Equals(Double.NaN));
Console.WriteLine("IsNaN: {0}", Double.IsNaN(Double.NaN));
Console.WriteLine("\nNaN > NaN: {0}", Double.NaN > Double.NaN);
Console.WriteLine("NaN >= NaN: {0}", Double.NaN >= Double.NaN);
Console.WriteLine("NaN < NaN: {0}", Double.NaN < Double.NaN);
Console.WriteLine("NaN < 100.0: {0}", Double.NaN < 100.0);
Console.WriteLine("NaN <= 100.0: {0}", Double.NaN <= 100.0);
Console.WriteLine("NaN >= 100.0: {0}", Double.NaN > 100.0);
Console.WriteLine("NaN.CompareTo(NaN): {0}", Double.NaN.CompareTo(Double.NaN));
Console.WriteLine("NaN.CompareTo(100.0): {0}", Double.NaN.CompareTo(100.0));
Console.WriteLine("(100.0).CompareTo(Double.NaN): {0}", (100.0).CompareTo(Double.NaN));
}
}输出：
NaN == NaN: False NaN != NaN: True NaN.Equals(NaN): True ! NaN.Equals(NaN): False IsNaN: True NaN > NaN: False NaN >= NaN: False NaN < NaN: False NaN < 100.0: False NaN <= 100.0: False NaN >= 100.0: False NaN.CompareTo(NaN): 0 NaN.CompareTo(100.0): -1 (100.0).CompareTo(Double.NaN): 1
