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

'Declaration
Public Shared Function ToDouble ( _
	value As Integer _
) As Double

Parameters

value
Type: System.Int32
A 32-bit signed integer.

Return Value

Type: System.Double
A double-precision floating point number equivalent to the value of value.

The following code sample illustrates the conversion of an Int32 value to a Double one, using ToDouble.


Public Sub ConvertDoubleInt(ByVal doubleVal As Double)

   Dim intVal As Integer = 0
   ' Double to Integer conversion can overflow.
   Try
      intVal = System.Convert.ToInt32(doubleVal)
      outputBlock.Text &= String.Format("{0} as an Integer is: {1}", _
                                doubleVal, intVal) & vbCrLf
   Catch exception As System.OverflowException
      outputBlock.Text &= String.Format( _
          "Overflow in Double-to-Byte conversion.") & vbCrLf
   End Try

   ' Integer to Double conversion cannot overflow.
   doubleVal = System.Convert.ToDouble(intVal)
   outputBlock.Text &= String.Format("{0} as a Double is: {1}", _
                             intVal, doubleVal) & vbCrLf
End Sub
