Een getal dat het teken aangeeft van value, zoals wordt weergegeven in de volgende tabel.

Retourwaarde	Betekenis
-1	`value` is kleiner dan nul.
0	`value` is gelijk aan nul.
1	`value` is groter dan nul.

Voorbeelden

In het volgende voorbeeld ziet u hoe u de Sign(Decimal) methode gebruikt om het teken van een Decimal waarde te bepalen en weer te geven aan de console.
