# 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

```static implicit operator Decimal (
unsigned long long 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 op_Implicit conversion from unsigned __int64 to
// Decimal.
using namespace System;
#define formatter "{0,20}{1,21}{2,10:X8}{3,9:X8}{4,9:X8}{5,9:X8}"

// Convert the unsigned __int64 argument and display the Decimal value.
void DecimalFromInt64( unsigned __int64 argument )
{
Decimal decValue;
array<Int32>^bits;

// The compiler invokes a constructor in the Managed Extensions
// for C++ unless op_Implicit is explicitly called.
decValue = argument;

// Display the Decimal and its binary representation.
bits = Decimal::GetBits( decValue );
Console::WriteLine( formatter, argument, decValue, bits[ 3 ], bits[ 2 ], bits[ 1 ], bits[ 0 ] );
}

int main()
{
Console::WriteLine( "This example of the op_Implicit conversion from unsigned "
"__int64 to Decimal \ngenerates the following output. "
"It displays the Decimal value and its \nbinary "
"representation.\n" );
Console::WriteLine( formatter, "unsigned __int64", "Decimal value", "bits[3]", "bits[2]", "bits[1]", "bits[0]" );
Console::WriteLine( formatter, "----------------", "-------------", "-------", "-------", "-------", "-------" );

// Convert unsigned __int64 values and display the results.
DecimalFromInt64( UInt64::MinValue );
DecimalFromInt64( UInt64::MaxValue );
DecimalFromInt64( 0xFFFFFFFFFFFF );
DecimalFromInt64( 123456789123456789 );
DecimalFromInt64( 1000000000000000 );
}
