Public Shared Function ToString ( _
	value As Double _
) As String


Type: System.Double
A double-precision floating point number.

Return Value

This implementation is identical to Double.ToString.

The following code sample illustrates the conversion of a Double to a String, using ToString.

Public Sub ConvertDoubleString(ByVal doubleVal As Double)

   Dim stringVal As String

   ' A conversion from Double to String cannot overflow.       
   stringVal = System.Convert.ToString(doubleVal)
   outputBlock.Text &= String.Format("{0} as a String is: {1}", _
                             doubleVal, stringVal) & vbCrLf

      doubleVal = System.Convert.ToDouble(stringVal)
      outputBlock.Text &= String.Format("{0} as a Double is: {1}", _
                                stringVal, doubleVal) & vbCrLf
   Catch exception As System.OverflowException
      outputBlock.Text &= String.Format( _
          "Overflow in String-to-Double conversion.") & vbCrLf
   Catch exception As System.FormatException
      outputBlock.Text &= String.Format( _
          "The string is not formatted as a Double.") & vbCrLf
   Catch exception As System.ArgumentException
      outputBlock.Text &= "The string is null." & vbCrLf
   End Try

End Sub
