jpayne@69 52 * This class represents the set of symbols needed by DecimalFormat
jpayne@69 53 * to format numbers. DecimalFormat creates for itself an instance of
jpayne@69 54 * DecimalFormatSymbols from its locale data. If you need to change any
jpayne@69 55 * of these symbols, you can get the DecimalFormatSymbols object from
jpayne@69 56 * your DecimalFormat and modify it.
jpayne@69 57 * <P>
jpayne@69 58 * Here are the special characters used in the parts of the
jpayne@69 59 * subpattern, with notes on their usage.
jpayne@69 60 * <pre>
jpayne@69 61 * \code
jpayne@69 62 * Symbol Meaning
jpayne@69 63 * 0 a digit
jpayne@69 64 * # a digit, zero shows as absent
jpayne@69 65 * . placeholder for decimal separator
jpayne@69 66 * , placeholder for grouping separator.
jpayne@69 67 * ; separates formats.
jpayne@69 68 * - default negative prefix.
jpayne@69 69 * % divide by 100 and show as percentage
jpayne@69 70 * X any other characters can be used in the prefix or suffix
jpayne@69 71 * ' used to quote special characters in a prefix or suffix.
jpayne@69 72 * \endcode
jpayne@69 73 * </pre>
jpayne@69 74 * [Notes]
jpayne@69 75 * <P>
jpayne@69 76 * If there is no explicit negative subpattern, - is prefixed to the
jpayne@69 77 * positive form. That is, "0.00" alone is equivalent to "0.00;-0.00".
jpayne@69 78 * <P>
jpayne@69 79 * The grouping separator is commonly used for thousands, but in some
jpayne@69 80 * countries for ten-thousands. The interval is a constant number of
jpayne@69 81 * digits between the grouping characters, such as 100,000,000 or 1,0000,0000.
jpayne@69 82 * If you supply a pattern with multiple grouping characters, the interval
jpayne@69 83 * between the last one and the end of the integer is the one that is
jpayne@69 84 * used. So "#,##,###,####" == "######,####" == "##,####,####".
