Decimal.Truncate-Methode

Gibt den ganzzahligen Teil des angegebenen Decimal zurück; Bruchziffern werden verworfen.

Namespace: System
Assembly: mscorlib (in mscorlib.dll)

Syntax

'Declaration
Public Shared Function Truncate ( _
    d As Decimal _
) As Decimal
'Usage
Dim d As Decimal
Dim returnValue As Decimal

returnValue = Decimal.Truncate(d)
public static decimal Truncate (
    decimal d
)
public:
static Decimal Truncate (
    Decimal d
)
public static Decimal Truncate (
    Decimal d
)
public static function Truncate (
    d : decimal
) : decimal

Parameter

Rückgabewert

Das Decimal-Ergebnis der Rundung von d auf die nächste ganze Zahl in Richtung 0.

Hinweise

Diese Methode rundet d auf die nächste ganze Zahl in Richtung 0. Dies bedeutet, dass Ziffern hinter dem Dezimaltrennzeichen weggelassen werden.

Beispiel

Im folgenden Codebeispiel werden die Nachkommastellen von mehreren Decimal-Werten mithilfe der Truncate-Methode entfernt.
