# Decimal Implicit Conversion (UInt64 to Decimal)

Silverlight

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
A 64-bit unsigned integer.

#### Return Value

Type: System.Decimal
A Decimal that represents 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 Example
{
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(System.Windows.Controls.TextBlock outputBlock, ulong argument)
{
decimal decValue;
int[] bits;

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

outputBlock.Text += String.Format(formatter, argument, decValue,
bits[3], bits[2], bits[1], bits[0]) + "\n";
}

public static void Demo(System.Windows.Controls.TextBlock outputBlock)
{
outputBlock.Text += String.Format(
"This example of the implicit conversion from ulong " +
"to decimal generates the \nfollowing output. It " +
"displays the decimal value and its binary " +
"representation.\n") + "\n";
outputBlock.Text += String.Format(formatter, "ulong argument",
"decimal value", "bits[3]", "bits[2]",
"bits[1]", "bits[0]") + "\n";
outputBlock.Text += String.Format(formatter, "--------------",
"-------------", "-------", "-------",
"-------", "-------") + "\n";

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