示例1:
Dim zero As Double = 0
' This condition will return false.
If (0 / zero) = Double.NaN Then
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.")
End If示例2:
Dim nan1 As Double = 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3: Example
Module Example
Public Sub 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("Not NaN.Equals(NaN): {0}", Not Double.NaN.Equals(Double.NaN))
Console.WriteLine("IsNaN: {0}", Double.IsNaN(Double.NaN))
Console.WriteLine()
Console.WriteLine("NaN > NaN: {0}", Double.NaN > 100.0)
Console.WriteLine("NaN >= NaN: {0}", Double.NaN >= 100.0)
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))
End Sub
End Module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
