+/**
+ * This class represents the set of symbols needed by DecimalFormat
+ * to format numbers. DecimalFormat creates for itself an instance of
+ * DecimalFormatSymbols from its locale data.  If you need to change any
+ * of these symbols, you can get the DecimalFormatSymbols object from
+ * your DecimalFormat and modify it.
+ * <P>
+ * Here are the special characters used in the parts of the
+ * subpattern, with notes on their usage.
+ * <pre>
+ * \code
+ *        Symbol   Meaning
+ *          0      a digit
+ *          #      a digit, zero shows as absent
+ *          .      placeholder for decimal separator
+ *          ,      placeholder for grouping separator.
+ *          ;      separates formats.
+ *          -      default negative prefix.
+ *          %      divide by 100 and show as percentage
+ *          X      any other characters can be used in the prefix or suffix
+ *          '      used to quote special characters in a prefix or suffix.
+ * \endcode
+ *  </pre>
+ * [Notes]
+ * <P>
+ * If there is no explicit negative subpattern, - is prefixed to the
+ * positive form. That is, "0.00" alone is equivalent to "0.00;-0.00".
+ * <P>
+ * The grouping separator is commonly used for thousands, but in some
+ * countries for ten-thousands. The interval is a constant number of
+ * digits between the grouping characters, such as 100,000,000 or 1,0000,0000.
+ * If you supply a pattern with multiple grouping characters, the interval
+ * between the last one and the end of the integer is the one that is
+ * used. So "#,##,###,####" == "######,####" == "##,####,####".
