# Decimal.op_Equality Method

.NET Framework 3.0
Returns a value indicating whether two instances of Decimal are equal.

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

## Syntax

```public static bool operator == (
decimal d1,
decimal d2
)
```
```Not applicable.
```

d1

A Decimal.

d2

A Decimal.

#### Return Value

true if d1 and d2 are equal; otherwise, false.

## Example

The following code example compares several Decimal values to a reference Decimal value using the Equality operator.

```// Example of the decimal relational operators.
using System;

class DecRelationalOpsDemo
{
const string dataFmt = "{0,43}    {1}" ;

// Compare decimal parameters, and display them with the results.
static void CompareDecimals( decimal Left, decimal Right,
string RightText )
{
Console.WriteLine( );
Console.WriteLine( dataFmt, "Right: " + RightText, Right );
Console.WriteLine( dataFmt, "Left == Right", Left == Right );
Console.WriteLine( dataFmt, "Left >  Right", Left > Right );
Console.WriteLine( dataFmt, "Left >= Right", Left >= Right );
Console.WriteLine( dataFmt, "Left != Right", Left != Right );
Console.WriteLine( dataFmt, "Left <  Right", Left < Right );
Console.WriteLine( dataFmt, "Left <= Right", Left <= Right );
}

static void Main( )
{
decimal Left = new decimal( 123.456 );

Console.WriteLine(

"different decimal values \nand compares them with " +
"the following reference value.\n" );
Console.WriteLine( dataFmt,
"Left: decimal( 123.456 )", Left );

// Create objects to compare with a 2-hour decimal.

"decimal( 1.23456E+2 )" );
