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

public static explicit operator decimal (float value);

static member op_Explicit : single -> decimal

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

Parameter

value: Single

Angka floating-point presisi tunggal untuk dikonversi.

Mengembalikan

Decimal

Angka titik mengambang presisi tunggal yang dikonversi.

Pengecualian

OverflowException

value lebih besar dari Decimal.MaxValue atau kurang dari Decimal.MinValue.

-atau-

value adalah NaN, PositiveInfinity, atau NegativeInfinity.

Contoh

Contoh berikut mengonversi Single nilai menjadi Decimal angka dengan menggunakan Single operator ke Decimal konversi. Konversi ini memerlukan operator op_Explicit di 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 );
   DecimalFromSingle( 1.234567E+12F );
   DecimalFromSingle( 1.2345678E+28F );
   DecimalFromSingle( 1.2345678E+30F );

Keterangan

Operator ini mendukung konversi eksplisit ke Decimal UInt64. Sintaks untuk konversi eksplisit tersebut bergantung pada bahasa, dan pengkompilasi bahasa individual dapat memberikan implementasi yang berbeda dan mengembalikan hasil yang berbeda. Contoh ini mengilustrasikan nilai pengembalian yang berbeda saat Anda secara eksplisit mengonversi Decimal nilai menjadi UInt64 nilai dengan menggunakan C# dan Visual Basic. Untuk melakukan konversi yang tidak bergantung pada bahasa, Anda dapat memanggil Decimal.ToUInt64(Decimal) atau Convert.ToUInt64(Decimal) metode .

Keterangan

Operator ini mendukung konversi eksplisit ke Decimal UInt16. Sintaks untuk konversi eksplisit tersebut bergantung pada bahasa, dan pengkompilasi bahasa individual dapat memberikan implementasi yang berbeda dan mengembalikan hasil yang berbeda. Contoh ini mengilustrasikan nilai pengembalian yang berbeda saat Anda secara eksplisit mengonversi Decimal nilai menjadi UInt16 nilai dengan menggunakan C# dan Visual Basic. Untuk melakukan konversi yang tidak bergantung pada bahasa, Anda dapat memanggil Decimal.ToUInt16(Decimal) atau Convert.ToUInt16(Decimal) metode .

Keterangan

Operator ini mendukung konversi eksplisit ke Decimal SByte. Sintaks untuk konversi eksplisit tersebut bergantung pada bahasa, dan pengkompilasi bahasa individual dapat memberikan implementasi yang berbeda dan mengembalikan hasil yang berbeda. Contoh ini mengilustrasikan nilai pengembalian yang berbeda saat Anda secara eksplisit mengonversi Decimal nilai menjadi Byte dan SByte nilai dengan menggunakan C# dan Visual Basic. Untuk melakukan konversi yang tidak bergantung pada bahasa, Anda dapat memanggil Decimal.ToSByte(Decimal) metode atau Convert.ToSByte(Decimal) metode .

Keterangan

Operasi ini dapat mengakibatkan hilangnya presisi, karena angka floating-point presisi tunggal memiliki lebih sedikit digit signifikan daripada Decimal.

Operator ini mendukung konversi eksplisit ke Decimal Single. Sintaks untuk konversi eksplisit tersebut bergantung pada bahasa, dan pengkompilasi bahasa individu dapat memberikan implementasi yang berbeda dan mengembalikan hasil yang berbeda. Contoh ini mengilustrasikan nilai pengembalian yang berbeda saat Anda secara eksplisit mengonversi Decimal nilai menjadi Single nilai dengan menggunakan C# dan Visual Basic. Untuk melakukan konversi yang tidak bergantung pada bahasa, Anda dapat memanggil Decimal.ToSingle(Decimal) atau Convert.ToSingle(Decimal) metode .

Keterangan

Operator ini mendukung konversi eksplisit ke Decimal Int32. Sintaks untuk konversi eksplisit tersebut bergantung pada bahasa, dan pengkompilasi bahasa individu dapat memberikan implementasi yang berbeda dan mengembalikan hasil yang berbeda. Contoh ini mengilustrasikan nilai pengembalian yang berbeda saat Anda secara eksplisit mengonversi Decimal nilai menjadi Int32 nilai dengan menggunakan C#, C++, dan Visual Basic. Untuk melakukan konversi yang tidak bergantung pada bahasa, Anda dapat memanggil Decimal.ToInt32(Decimal) atau Convert.ToInt32(Decimal) metode .

Keterangan

Operasi ini dapat mengakibatkan hilangnya presisi, karena angka floating-point presisi ganda memiliki lebih sedikit Decimaldigit signifikan daripada .

Operator ini mendukung konversi eksplisit ke Decimal Double. Sintaks untuk konversi eksplisit tersebut bergantung pada bahasa, dan pengkompilasi bahasa individu dapat memberikan implementasi yang berbeda dan mengembalikan hasil yang berbeda. Contoh ini mengilustrasikan nilai pengembalian yang berbeda saat Anda secara eksplisit mengonversi Decimal nilai menjadi Double nilai dengan menggunakan C#, C++, dan Visual Basic. Untuk melakukan konversi yang tidak bergantung pada bahasa, Anda dapat memanggil Decimal.ToDouble(Decimal) atau Convert.ToDouble(Decimal) metode .

Keterangan

Operator ini mendukung konversi eksplisit ke Decimal Byte. Sintaks untuk konversi eksplisit tersebut bergantung pada bahasa, dan pengkompilasi bahasa individu dapat memberikan implementasi yang berbeda dan mengembalikan hasil yang berbeda. Contoh ini mengilustrasikan nilai pengembalian yang berbeda saat Anda secara eksplisit mengonversi Decimal nilai menjadi Byte nilai dengan menggunakan C#, C++, dan Visual Basic. Untuk melakukan konversi yang tidak bergantung pada bahasa, Anda dapat memanggil Decimal.ToByte(Decimal) atau Convert.ToByte(Decimal) metode .
