範例

下列程式代碼範例說明 如何使用 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() + ".")

備註

這個常數的值是將負數除以零所得。

當運算結果小於 Double.MinValue時，此常數會回傳。

用 IsNegativeInfinity 來判斷一個值是否被評為負無限大。
