Double.PositiveInfinity 字段

定义

重要

一些信息与预发行产品相关，相应产品在发行之前可能会进行重大修改。对于此处提供的信息，Microsoft 不作任何明示或暗示的担保。

表示正无穷。此字段为常数。

public: double PositiveInfinity = Infinity;

public const double PositiveInfinity = Infinity;

val mutable PositiveInfinity : double

Public Const PositiveInfinity As Double  = Infinity

Value = Infinity

Double

以下代码示例演示了的用法 PositiveInfinity：

// This will equal Infinity.
Console::WriteLine( "PositiveInfinity plus 10.0 equals {0}.", (Double::PositiveInfinity + 10.0) );

// This will equal Infinity.
Console.WriteLine("PositiveInfinity plus 10.0 equals {0}.", (Double.PositiveInfinity + 10.0).ToString());

// This will equal Infinity.
printfn $"PositiveInfinity plus 10.0 equals {Double.PositiveInfinity + 10.}."

' This will equal Infinity.
Console.WriteLine("PositiveInfinity plus 10.0 equals " + (Double.PositiveInfinity + 10).ToString() + ".")

此常量的值是将正数除以零的结果。

当操作的结果大于 Double.MaxValue时，将返回此常量。

使用 IsPositiveInfinity 确定值的计算结果是否为正无穷大。
