Retourne le résultat de la multiplication de la valeur Decimal spécifiée par 1 négatif.
public:
static System::Decimal Negate(System::Decimal d);public static decimal Negate (decimal d);static member Negate : decimal -> decimalPublic Shared Function Negate (d As Decimal) As DecimalParamètres
- d
- Decimal
Valeur à rendre négative.
Retours
Nombre décimal ayant la valeur de d, mais le signe inverse.
- ou -
Zéro, si d est égal à zéro.
