Der Wert dieser Konstante ist negativ 1.7976931348623157 e + 308.The value of this constant is negative 1.7976931348623157E+308.

Das Ergebnis eines Vorgangs, der kleiner als Double.MinValue ist. Double.NegativeInfinityThe result of an operation that is less than Double.MinValue is Double.NegativeInfinity. Im folgenden Beispiel werden Ergebnisse Double.NegativeInfinity aus Subtraktions-und Multiplikations Vorgängen ausgegeben, wenn Double.MinValuedas Ergebnis kleiner als ist.In the following example, Double.NegativeInfinity results from subtraction and multiplication operations when the result is less than Double.MinValue.
