public:
static System::Decimal Negate(System::Decimal d);
public static decimal Negate (decimal d);
static member Negate : decimal -> decimal
Public Shared Function Negate (d As Decimal) As Decimal
Parametry
- d
- Decimal
Hodnota, jejíž negace má být vypočtena.
Návraty
Desítkové číslo s hodnotou d
, ale opačným znaménkem.
-nebo-
Nula, pokud d
je nula.
Příklady
Následující příklad kódu používá Negate
metodu ke změně znaménka více Decimal
hodnot.
