# Decimal Implicit Conversion (UInt64 to Decimal)

.NET Framework 4.5

Defines an explicit conversion of 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.

## Remarks

The overloads of the Implicit method define the types from which the compiler can automatically convert a Decimal value without an explicit casting operator (in C#) or a call to a conversion function (in Visual Basic). They are widening conversions that do not involve data loss and do not throw an OverflowException exception.

## Examples

The following example converts UInt64 values to Decimal numbers by using the UInt64 to Decimal conversion.

using System;

public class Example
{
public static void Main()
{
// Define an array of 64-bit unsigned integer values.
ulong[] values = { ulong.MinValue, ulong.MaxValue,
0xFFFFFFFFFFFF, 123456789123456789,
1000000000000000 };
// Convert each value to a Decimal.
foreach (var value in values) {
Decimal decValue = value;
Console.WriteLine("{0} ({1}) --> {2} ({3})", value,
value.GetType().Name, decValue,
decValue.GetType().Name);
}
}
}
// The example displays the following output:
//    0 (UInt64) --> 0 (Decimal)
//    18446744073709551615 (UInt64) --> 18446744073709551615 (Decimal)
//    281474976710655 (UInt64) --> 281474976710655 (Decimal)
//    123456789123456789 (UInt64) --> 123456789123456789 (Decimal)
//    1000000000000000 (UInt64) --> 1000000000000000 (Decimal)
