本文整理汇总了VB.NET中System.Double.NaN字段的典型用法代码示例。如果您正苦于以下问题：VB.NET Double.NaN字段的具体用法？VB.NET Double.NaN怎么用？VB.NET Double.NaN使用的例子？那么恭喜您, 这里精选的字段代码示例或许可以为您提供帮助。您也可以进一步了解该字段所在类System.Double的用法示例。

在下文中一共展示了Double.NaN字段的3个代码示例，这些例子默认根据受欢迎程度排序。您可以为喜欢或者感觉有用的代码点赞，您的评价将有助于我们的系统推荐出更棒的VB.NET代码示例。

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

开发者ID:VB.NET开发者，项目名称:System，代码行数:8，代码来源:Double.NaN

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))

开发者ID:VB.NET开发者，项目名称:System，代码行数:4，代码来源:Double.NaN

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
