# Decimal Implicit Conversion (UInt64 to Decimal)

Visual Studio 2010

Converts a 64-bit unsigned integer to a Decimal.

This API is not CLS-compliant.

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

## Syntax

```public static implicit operator decimal (
ulong value
)
```

#### Parameters

value
Type: System.UInt64
The 64-bit unsigned integer to convert.

#### Return Value

Type: System.Decimal
The converted 64-bit unsigned integer.

## Examples

The following code example converts UInt64 values to Decimal numbers using the UInt64 to Decimal conversion. This conversion is implicit in C#, but requires the op_Implicit operator in Visual Basic and C++. Implicit conversions to Decimal use other methods in these languages.

```
// Example of the implicit conversion from ulong to decimal.
using System;

class DecimalFromUInt64Demo
{
const string formatter =
"{0,20}{1,21}{2,10:X8}{3,9:X8}{4,9:X8}{5,9:X8}";

// Convert the ulong argument and display the decimal value.
public static void DecimalFromUInt64( ulong argument )
{
decimal decValue;
int[ ]  bits;

// Display the decimal and its binary representation.
decValue = argument;
bits = decimal.GetBits( decValue );

Console.WriteLine( formatter, argument, decValue,
bits[ 3 ], bits[ 2 ], bits[ 1 ], bits[ 0 ] );
}

public static void Main( )
{
Console.WriteLine(
"This example of the implicit conversion from ulong " +
"to decimal generates the \nfollowing output. It " +
"displays the decimal value and its binary " +
"representation.\n" );
Console.WriteLine( formatter, "ulong argument",
"decimal value", "bits[3]", "bits[2]",
"bits[1]", "bits[0]" );
Console.WriteLine( formatter, "--------------",
"-------------", "-------", "-------",
"-------", "-------" );

// Convert ulong values and display the results.
DecimalFromUInt64( ulong.MinValue );
DecimalFromUInt64( ulong.MaxValue );
DecimalFromUInt64( 0xFFFFFFFFFFFF );
DecimalFromUInt64( 123456789123456789 );
DecimalFromUInt64( 1000000000000000 );
}
}
