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 -> decimal

Public Shared Function Negate (d As Decimal) As Decimal

Parameters

d: Decimal

The value to negate.

Returns

Decimal

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.

// Example of the Decimal::Negate, Decimal::Floor, and 
// Decimal::Truncate methods.

   Console::WriteLine( dataFmt, "Decimal::Floor( Argument )", Decimal::Floor( Argument ) );
   Console::WriteLine( dataFmt, "Decimal::Truncate( Argument )", Decimal::Truncate( Argument ) );
