# Decimal.Subtraction Operator

.NET Framework 4

Subtracts two specified Decimal values.

Namespace:  System
Assembly:  mscorlib (in mscorlib.dll)
```public static decimal operator -(
decimal d1,
decimal d2
)
```

#### Parameters

d1
Type: System.Decimal
The minuend.
d2
Type: System.Decimal
The subtrahend.

#### Return Value

Type: System.Decimal
The result of subtracting d2 from d1.
ExceptionCondition
OverflowException

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

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

```
// Example of the decimal addition and subtraction operators.
using System;

{
const string dataFmt = "   {0,-18}{1,31}" ;

// Display decimal parameters and their sum and difference.
static void ShowDecimalSumDiff( decimal Left, decimal Right )
{
Console.WriteLine( );
Console.WriteLine( dataFmt, "decimal Left", Left );
Console.WriteLine( dataFmt, "decimal Right", Right );
Console.WriteLine( dataFmt, "Left + Right",
Left + Right );
Console.WriteLine( dataFmt, "Left - Right",
Left - Right );
}

static void Main( )
{
Console.WriteLine( "This example of the decimal " +
"addition and subtraction operators \ngenerates the " +
"following output. It displays the sum and \n" +
"difference of several pairs of decimal objects."  );

// Create pairs of decimal objects.
ShowDecimalSumDiff(
new decimal( 1230000000, 0, 0, false, 7 ),
0.0012300M );
ShowDecimalSumDiff( 123.456789M, 0.006789M );
ShowDecimalSumDiff( 12345678900000000M,
0.00000000123456789M );
ShowDecimalSumDiff( 123456789.0123456789M,
123456789.1123456789M );
}
}
