public:
static System::Decimal Multiply(System::Decimal d1, System::Decimal d2);public static decimal Multiply (decimal d1, decimal d2);static member Multiply : decimal * decimal -> decimalPublic Shared Function Multiply (d1 As Decimal, d2 As Decimal) As DecimalParametri
- d1
- Decimal
Moltiplicando.
- d2
- Decimal
Moltiplicatore.
Restituisce
Risultato della moltiplicazione tra d1 e d2.
Eccezioni
Il valore restituito è minore di Decimal.MinValue o maggiore di Decimal.MaxValue.
Esempio
