Returns the result of multiplying the specified Decimal value by negative one.
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 DecimalParameters
- d
- Decimal
The value to negate.
Returns
A decimal number with the value of d, but the opposite sign.
-or-
Zero, if d is zero.
Examples
The following code example uses the Negate method to change the sign of several Decimal values.
