<DL>
<DD>Create a DecimalFormat from the given pattern and symbols.
 Use this constructor when you need to completely customize the
 behavior of the format.

 To obtain standard formats for a given
 locale, use the factory methods on NumberFormat such as
 getInstance or getCurrencyInstance. If you need only minor adjustments
 to a standard format, you can modify the format returned by
 a NumberFormat factory method.<DD><DL>
