# Decimal.Multiply Operator

Multiplies two specified Decimal values.

Namespace: System
Assembly: mscorlib (in mscorlib.dll)

## Syntax

``````Public Shared Operator * ( _
d1 As Decimal, _
d2 As Decimal _
) As Decimal
``````
``````public static decimal operator *(
decimal d1,
decimal d2
)
``````

#### Return Value

Type: System..::.Decimal
The Decimal result of multiplying d1 by d2.

## Exceptions

Exception Condition
OverflowException

The return value is less than MinValue or greater than MaxValue.

## Examples

The following code example creates several pairs of Decimal values and calculates their products with the Multiplication operator.

``````Module Example
Const dataFmt As String = "{0,-38}{1,31}"

Sub ShowDecimalProQuoRem(ByVal outputBlock As System.Windows.Controls.TextBlock, _
