Single.NegativeInfinity 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。

表示负无穷。此字段为常数。

public: float NegativeInfinity = -Infinity;

public const float NegativeInfinity = -Infinity;

val mutable NegativeInfinity : single

Public Const NegativeInfinity As Single  = -Infinity

Value = -Infinity

Single

下面的代码示例演示常 NegativeInfinity 量。

// This will equal Infinity.
Console::WriteLine( "10.0 minus NegativeInfinity equals {0}.", (10.0 - Single::NegativeInfinity) );

// This will equal Infinity.
Console.WriteLine("10.0 minus NegativeInfinity equals {0}.", (10.0 - Single.NegativeInfinity).ToString());

// This will equal Infinity.
printfn $"10.0 minus NegativeInfinity equals {10f - Single.NegativeInfinity}."

' This will equal Infinity.
Console.WriteLine("10.0 minus NegativeInfinity equals " + (10 - Single.NegativeInfinity).ToString() + ".")

此常量的值是将负数除以零的结果。

当操作的结果小于 MinValue时，将返回此常量。

用于 IsNegativeInfinity 确定值的计算结果是否为负无穷大。
