This method is intended for use in conjunction with #putDouble. If the implementation supports stored defaults and such a default exists, is accessible, and could be converted to a double with Double.parseDouble, this double is returned in preference to the specified default. Java documentation ...

To interpret localized string representations of a floating-point value, use subclasses ofjava.text.NumberFormat. Note that trailing format specifiers, specifiers that determine the type of a floating-point literal (1.0fis afloatvalue;1.0dis adoublevalue), do not influence the results of this method...
