Single.NegativeInfinity 字段

定义

表示负无穷。Represents negative infinity. 此字段为常数。This field is constant.

public: float NegativeInfinity = -Infinity;

public const float NegativeInfinity = -Infinity;

val mutable NegativeInfinity : single

Public Const NegativeInfinity As Single  = -Infinity

下面的代码示例演示了 NegativeInfinity 常数。The following code example demonstrates the NegativeInfinity constant.

// 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.
Console.WriteLine("10.0 minus NegativeInfinity equals " + (10 - Single.NegativeInfinity).ToString() + ".")

此常量的值是负数除以零所得的结果。The value of this constant is the result of dividing a negative number by zero.

当操作的结果小于时，将返回此常数 MinValue 。This constant is returned when the result of an operation is less than MinValue.

用于 IsNegativeInfinity 确定某个值是否计算为负无穷大。Use IsNegativeInfinity to determine whether a value evaluates to negative infinity.
