Examples

The following example converts Single values to Decimal numbers by using the Single to Decimal conversion operator. This conversion requires the op_Explicit operator in Visual Basic.

// Example of the explicit conversion from float to Decimal.
using namespace System;
#define formatter "{0,16:E7}{1,33}"

// Get the exception type name; remove the namespace prefix.
String^ GetExceptionType( Exception^ ex )

   String^ exceptionType = ex->GetType()->ToString();
   return exceptionType->Substring( exceptionType->LastIndexOf( '.' ) + 1 );
}


// Convert the float argument; catch exceptions that are thrown.
void DecimalFromSingle( float argument )
{
   Object^ decValue;
   
   // Convert the float argument to a Decimal value.
   try
   {
      decValue = (Decimal)argument;
   }
   catch ( Exception^ ex ) 
   {
      decValue = GetExceptionType( ex );
   }

   Console::WriteLine( formatter, argument, decValue );
}

int main()
{
   Console::WriteLine( "This example of the explicit conversion from float "
   "to Decimal \ngenerates the following output.\n" );
   Console::WriteLine( formatter, "float argument", "Decimal value" );
   Console::WriteLine( formatter, "--------------", "-------------" );
   
   // Convert float values and display the results.
   DecimalFromSingle( 1.2345E-30F );
   DecimalFromSingle( 1.2345E-26F );
   DecimalFromSingle( 1.23456E-22F );
   DecimalFromSingle( 1.23456E-12F );
   DecimalFromSingle( 1.234567F );

Remarks

This operator supports the explicit conversion of a Decimal to a UInt64. The syntax for such explicit conversions is language-dependent, and individual language compilers can provide different implementations and return different results. The example illustrates the different return values when you explicitly convert a Decimal value to a UInt64 value by using C# and Visual Basic. To perform a conversion that is independent of language, you can call the Decimal.ToUInt64(Decimal) or the Convert.ToUInt64(Decimal) method.

Remarks

This operator supports the explicit conversion of a Decimal to a UInt16. The syntax for such explicit conversions is language-dependent, and individual language compilers can provide different implementations and return different results. The example illustrates the different return values when you explicitly convert a Decimal value to a UInt16 value by using C# and Visual Basic. To perform a conversion that is independent of language, you can call the Decimal.ToUInt16(Decimal) or the Convert.ToUInt16(Decimal) method.

'       OverflowException: Cannot convert -129

Remarks

This operator supports the explicit conversion of a Decimal to a SByte. The syntax for such explicit conversions is language-dependent, and individual language compilers can provide different implementations and return different results. The example illustrates the different return values when you explicitly convert a Decimal value to a Byte and an SByte value by using C# and Visual Basic. To perform a conversion that is independent of language, you can call the Decimal.ToSByte(Decimal) method or the Convert.ToSByte(Decimal) method.

Remarks

This operation can result in a loss of precision, because a single-precision floating-point number has fewer significant digits than a Decimal.

This operator supports the explicit conversion of a Decimal to a Single. The syntax for such explicit conversions is language-dependent, and individual language compilers can provide different implementations and return different results. The example illustrates the different return values when you explicitly convert a Decimal value to a Single value by using C# and Visual Basic. To perform a conversion that is independent of language, you can call the Decimal.ToSingle(Decimal) or the Convert.ToSingle(Decimal) method.

Remarks

This operator supports the explicit conversion of a Decimal to an Int32. The syntax for such explicit conversions is language-dependent, and individual language compilers can provide different implementations and return different results. The example illustrates the different return values when you explicitly convert a Decimal value to an Int32 value by using C#, C++, and Visual Basic. To perform a conversion that is independent of language, you can call the Decimal.ToInt32(Decimal) or the Convert.ToInt32(Decimal) method.

Remarks

This operation can result in a loss of precision, because a double-precision floating-point number has fewer significant digits than a Decimal.

This operator supports the explicit conversion of a Decimal to a Double. The syntax for such explicit conversions is language-dependent, and individual language compilers can provide different implementations and return different results. The example illustrates the different return values when you explicitly convert a Decimal value to a Double value by using C#, C++, and Visual Basic. To perform a conversion that is independent of language, you can call the Decimal.ToDouble(Decimal) or the Convert.ToDouble(Decimal) method.

To perform a conversion that is independent of language, you can call the Decimal.ToByte(Decimal) or the Convert.ToByte(Decimal) method.

Applies to

Explicit(Decimal to Int64)

Source:: Decimal.cs

Source:: Decimal.cs

Source:: Decimal.cs

Defines an explicit conversion of a Decimal to a 64-bit signed integer.

public:
 static explicit operator long(System::Decimal value);

public static explicit operator long (decimal value);

static member op_Explicit : decimal -> int64

Public Shared Narrowing Operator CType (value As Decimal) As Long

Parameters

value: Decimal

The value to convert.

Returns

Int64

A 64-bit signed integer that represents the converted Decimal.

Exceptions

OverflowException

value is less than Int64.MinValue or greater than Int64.MaxValue.

Examples

The following example converts Decimal numbers to Int64 values by using the explicit Decimal to Int64 conversion operator.

// Example of the explicit conversions from Decimal to __int64 and 
// Decimal to unsigned __int64.
using namespace System;
#define formatter "{0,25}{1,22}{2,22}"

// Get the exception type name; remove the namespace prefix.
String^ GetExceptionType( Exception^ ex )
{
   String^ exceptionType = ex->GetType()->ToString();
   return exceptionType->Substring( exceptionType->LastIndexOf( '.' ) + 1 );
}


// Convert the Decimal argument; catch exceptions that are thrown.
void DecimalToU_Int64( Decimal argument )
{
   Object^ Int64Value;
   Object^ UInt64Value;
   
   // Convert the argument to an __int64 value.

Remarks

This operator supports the explicit conversion of a Decimal to an Int64. The syntax for such explicit conversions is language-dependent, and individual language compilers can provide different implementations and return different results. The example illustrates the different return values when you explicitly convert a Decimal value to an Int64 value by using C# and Visual Basic. To perform a conversion that is independent of language, you can call the Decimal.ToInt64(Decimal) or the Convert.ToInt64(Decimal) method.
