表示负无穷。此字段为常数。

public: double NegativeInfinity = -Infinity;

public const double NegativeInfinity = -Infinity;

val mutable NegativeInfinity : double

Public Const NegativeInfinity As Double  = -Infinity

Value = -Infinity

下面的代码示例演示如何使用 NegativeInfinity：

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

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

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

' This will equal Infinity.
Console.WriteLine("10.0 minus NegativeInfinity equals " + (10 - Double.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 Double.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。
