# Decimal.Equals Method (Decimal, Decimal)

Visual Studio 2010

Returns a value indicating whether two specified instances of Decimal represent the same value.

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

## Syntax

```public static bool Equals(
decimal d1,
decimal d2
)
```

#### Parameters

d1
Type: System.Decimal
The first value to compare.
d2
Type: System.Decimal
The second value to compare.

#### Return Value

Type: System.Boolean
true if d1 and d2 are equal; otherwise, false.

## Examples

The following code example compares several Decimal values to a reference Decimal value using the static Equals method.

```
// Example of the decimal.Compare and static decimal.Equals methods.
using System;

class DecCompareEqualsDemo
{
const string dataFmt = "{0,-45}{1}";

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

public static void Main( )
{
Console.WriteLine( "This example of the " +
"decimal.Equals( decimal, decimal ) and \n" +
"decimal.Compare( decimal, decimal ) methods " +
"generates the \nfollowing output. It creates several " +
"different decimal \nvalues and compares them with " +
"the following reference value.\n" );

// Create a reference decimal value.
decimal Left = new decimal( 123.456 );

Console.WriteLine( dataFmt, "Left: decimal( 123.456 )",
Left );

// Create decimal values to compare with the reference.
CompareDecimals( Left, new decimal( 1.2345600E+2 ),
"decimal( 1.2345600E+2 )" );
CompareDecimals( Left, 123.4561M, "123.4561M" );
CompareDecimals( Left, 123.4559M, "123.4559M" );
CompareDecimals( Left, 123.456000M, "123.456000M" );
CompareDecimals( Left,
new decimal( 123456000, 0, 0, false, 6 ),
"decimal( 123456000, 0, 0, false, 6 )" );
}
}

/*
This example of the decimal.Equals( decimal, decimal ) and
decimal.Compare( decimal, decimal ) methods generates the
following output. It creates several different decimal
values and compares them with the following reference value.

Left: decimal( 123.456 )                     123.456

Right: decimal( 1.2345600E+2 )               123.456
decimal.Equals( Left, Right )                True
decimal.Compare( Left, Right )               0

Right: 123.4561M                             123.4561
decimal.Equals( Left, Right )                False
decimal.Compare( Left, Right )               -1

Right: 123.4559M                             123.4559
decimal.Equals( Left, Right )                False
decimal.Compare( Left, Right )               1
