Decimal Implicit Conversion (Int32 to Decimal)

Microsoft Silverlight will reach end of support after October 2021. Learn more.

Converts a 32-bit signed integer to a Decimal.

Namespace:  System
Assembly:  mscorlib (in mscorlib.dll)

Syntax

'Declaration
Public Shared Widening Operator CType ( _
    value As Integer _
) As Decimal
public static implicit operator decimal (
    int value
)

Parameters

Return Value

Type: System.Decimal
A Decimal that represents the converted 32-bit signed integer.

Examples

The following code example converts Int32 values to Decimal numbers using the Int32 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 Integer to Decimal.

Module Example

   Const formatter As String = _
       "{0,16}{1,15}{2,10:X8}{3,9:X8}{4,9:X8}{5,9:X8}"

   ' Convert the Integer argument and display the Decimal value.
   Sub DecimalFromInt32(ByVal outputBlock As System.Windows.Controls.TextBlock, ByVal argument As Integer)

      Dim decValue As Decimal
      Dim bits() As Integer

      ' The compiler invokes a constructor in Visual Basic 
      ' unless op_Implicit is explicitly called.
      decValue = Decimal.op_Implicit(argument)

      ' Display the Decimal and its binary representation.
      bits = Decimal.GetBits(decValue)
      outputBlock.Text &= String.Format(formatter, argument, decValue, _
          bits(3), bits(2), bits(1), bits(0)) & vbCrLf
   End Sub

   Public Sub Demo(ByVal outputBlock As System.Windows.Controls.TextBlock)

      outputBlock.Text &= String.Format( _
          "This example of the op_Implicit conversion from " & _
          "Integer to Decimal " & vbCrLf & "generates the " & _
          "following output. It displays the Decimal value and " & _
          vbCrLf & "its binary representation." & vbCrLf) & vbCrLf
      outputBlock.Text &= String.Format(formatter, "Integer argument", _
          "Decimal value", "bits(3)", "bits(2)", _
          "bits(1)", "bits(0)") & vbCrLf
      outputBlock.Text &= String.Format(formatter, "----------------", _
          "-------------", "-------", "-------", _
          "-------", "-------") & vbCrLf

      ' Convert Integer values and display the results.
      DecimalFromInt32(outputBlock, Integer.MinValue)
      DecimalFromInt32(outputBlock, Integer.MaxValue)
      DecimalFromInt32(outputBlock, &HFFFFFF)
      DecimalFromInt32(outputBlock, 123456789)
      DecimalFromInt32(outputBlock, -1000000000)
   End Sub
End Module
