-/**
- * DecimalFormat is a concrete subclass of NumberFormat that formats decimal
- * numbers. It has a variety of features designed to make it possible to parse
- * and format numbers in any locale, including support for Western, Arabic, or
- * Indic digits.  It also supports different flavors of numbers, including
- * integers ("123"), fixed-point numbers ("123.4"), scientific notation
- * ("1.23E4"), percentages ("12%"), and currency amounts ("$123").  All of these
- * flavors can be easily localized.
- *
- * <p>To obtain a NumberFormat for a specific locale (including the default
- * locale) call one of NumberFormat's factory methods such as
- * createInstance(). Do not call the DecimalFormat constructors directly, unless
- * you know what you are doing, since the NumberFormat factory methods may
- * return subclasses other than DecimalFormat.
- *
- * <p><strong>Example Usage</strong>
- *
- * \code
- *     // Normally we would have a GUI with a menu for this
- *     int32_t locCount;
- *     const Locale* locales = NumberFormat::getAvailableLocales(locCount);
- * 
- *     double myNumber = -1234.56;
- *     UErrorCode success = U_ZERO_ERROR;
- *     NumberFormat* form;
- * 
- *     // Print out a number with the localized number, currency and percent
- *     // format for each locale.
- *     UnicodeString countryName;
- *     UnicodeString displayName;
- *     UnicodeString str;
- *     UnicodeString pattern;
- *     Formattable fmtable;
- *     for (int32_t j = 0; j < 3; ++j) {
- *         cout << endl << "FORMAT " << j << endl;
- *         for (int32_t i = 0; i < locCount; ++i) {
- *             if (locales[i].getCountry(countryName).size() == 0) {
- *                 // skip language-only
- *                 continue;
- *             }
- *             switch (j) {
- *             case 0:
- *                 form = NumberFormat::createInstance(locales[i], success ); break;
- *             case 1:
- *                 form = NumberFormat::createCurrencyInstance(locales[i], success ); break;
- *             default:
- *                 form = NumberFormat::createPercentInstance(locales[i], success ); break;
- *             }
- *             if (form) {
- *                 str.remove();
- *                 pattern = ((DecimalFormat*)form)->toPattern(pattern);
- *                 cout << locales[i].getDisplayName(displayName) << ": " << pattern;
- *                 cout << "  ->  " << form->format(myNumber,str) << endl;
- *                 form->parse(form->format(myNumber,str), fmtable, success);
- *                 delete form;  
- *             }
- *         }
- *     }
- * \endcode
- *
- * <p><strong>Patterns</strong>
- *
- * <p>A DecimalFormat consists of a <em>pattern</em> and a set of
- * <em>symbols</em>.  The pattern may be set directly using
- * applyPattern(), or indirectly using other API methods which
- * manipulate aspects of the pattern, such as the minimum number of integer
- * digits.  The symbols are stored in a DecimalFormatSymbols
- * object.  When using the NumberFormat factory methods, the
- * pattern and symbols are read from ICU's locale data.
- * 
- * <p><strong>Special Pattern Characters</strong>
- *
- * <p>Many characters in a pattern are taken literally; they are matched during
- * parsing and output unchanged during formatting.  Special characters, on the
- * other hand, stand for other characters, strings, or classes of characters.
- * For example, the '#' character is replaced by a localized digit.  Often the
- * replacement character is the same as the pattern character; in the U.S. locale,
- * the ',' grouping character is replaced by ','.  However, the replacement is
- * still happening, and if the symbols are modified, the grouping character
- * changes.  Some special characters affect the behavior of the formatter by
- * their presence; for example, if the percent character is seen, then the
- * value is multiplied by 100 before being displayed.
- *
- * <p>To insert a special character in a pattern as a literal, that is, without
- * any special meaning, the character must be quoted.  There are some exceptions to
- * this which are noted below.
- *
- * <p>The characters listed here are used in non-localized patterns.  Localized
- * patterns use the corresponding characters taken from this formatter's
- * DecimalFormatSymbols object instead, and these characters lose
- * their special status.  Two exceptions are the currency sign and quote, which
- * are not localized.

- *
- * <p>A DecimalFormat pattern contains a postive and negative
- * subpattern, for example, "#,##0.00;(#,##0.00)".  Each subpattern has a
- * prefix, a numeric part, and a suffix.  If there is no explicit negative
- * subpattern, the negative subpattern is the localized minus sign prefixed to the
- * positive subpattern. That is, "0.00" alone is equivalent to "0.00;-0.00".  If there
- * is an explicit negative subpattern, it serves only to specify the negative
- * prefix and suffix; the number of digits, minimal digits, and other
- * characteristics are ignored in the negative subpattern. That means that
- * "#,##0.0#;(#)" has precisely the same result as "#,##0.0#;(#,##0.0#)".
- *
- * <p>The prefixes, suffixes, and various symbols used for infinity, digits,
- * thousands separators, decimal separators, etc. may be set to arbitrary
- * values, and they will appear properly during formatting.  However, care must
- * be taken that the symbols and strings do not conflict, or parsing will be
- * unreliable.  For example, either the positive and negative prefixes or the
- * suffixes must be distinct for parse() to be able
- * to distinguish positive from negative values.  Another example is that the
- * decimal separator and thousands separator should be distinct characters, or
- * parsing will be impossible.
- *
- * <p>The <em>grouping separator</em> is a character that separates clusters of
- * integer digits to make large numbers more legible.  It commonly used for
- * thousands, but in some locales it separates ten-thousands.  The <em>grouping
- * size</em> is the number of digits between the grouping separators, such as 3
- * for "100,000,000" or 4 for "1 0000 0000". There are actually two different
- * grouping sizes: One used for the least significant integer digits, the
- * <em>primary grouping size</em>, and one used for all others, the
- * <em>secondary grouping size</em>.  In most locales these are the same, but
- * sometimes they are different. For example, if the primary grouping interval
- * is 3, and the secondary is 2, then this corresponds to the pattern
- * "#,##,##0", and the number 123456789 is formatted as "12,34,56,789".  If a
- * pattern contains multiple grouping separators, the interval between the last
- * one and the end of the integer defines the primary grouping size, and the
- * interval between the last two defines the secondary grouping size. All others
- * are ignored, so "#,##,###,####" == "###,###,####" == "##,#,###,####".
- *
- * <p>Illegal patterns, such as "#.#.#" or "#.###,###", will cause
- * DecimalFormat to set a failing UErrorCode.
- *
- * <p><strong>Pattern BNF</strong>
- *
- * <pre>
- * pattern    := subpattern (';' subpattern)?
- * subpattern := prefix? number exponent? suffix?
- * number     := (integer ('.' fraction)?) | sigDigits
- * prefix     := '\\u0000'..'\\uFFFD' - specialCharacters
- * suffix     := '\\u0000'..'\\uFFFD' - specialCharacters
- * integer    := '#'* '0'* '0'
- * fraction   := '0'* '#'*
- * sigDigits  := '#'* '@' '@'* '#'*
- * exponent   := 'E' '+'? '0'* '0'
- * padSpec    := '*' padChar
- * padChar    := '\\u0000'..'\\uFFFD' - quote
- * &nbsp;
- * Notation:
- *   X*       0 or more instances of X
- *   X?       0 or 1 instances of X
- *   X|Y      either X or Y
- *   C..D     any character from C up to D, inclusive
- *   S-T      characters in S, except those in T
- * </pre>
- * The first subpattern is for positive numbers. The second (optional)
- * subpattern is for negative numbers.
- * 
- * <p>Not indicated in the BNF syntax above:
- *
- * <ul><li>The grouping separator ',' can occur inside the integer and
- * sigDigits elements, between any two pattern characters of that
- * element, as long as the integer or sigDigits element is not
- * followed by the exponent element.
- *
- * <li>Two grouping intervals are recognized: That between the
- *     decimal point and the first grouping symbol, and that
- *     between the first and second grouping symbols. These
- *     intervals are identical in most locales, but in some
- *     locales they differ. For example, the pattern
- *     &quot;#,##,###&quot; formats the number 123456789 as
- *     &quot;12,34,56,789&quot;.</li>
- * 
- * <li>The pad specifier <code>padSpec</code> may appear before the prefix,
- * after the prefix, before the suffix, after the suffix, or not at all.
- *
- * <li>In place of '0', the digits '1' through '9' may be used to
- * indicate a rounding increment.
- * </ul>
- *
- * <p><strong>Parsing</strong>
- *
- * <p>DecimalFormat parses all Unicode characters that represent
- * decimal digits, as defined by u_charDigitValue().  In addition,
- * DecimalFormat also recognizes as digits the ten consecutive
- * characters starting with the localized zero digit defined in the
- * DecimalFormatSymbols object.  During formatting, the
- * DecimalFormatSymbols-based digits are output.
- *
- * <p>During parsing, grouping separators are ignored.
- *
- * <p>If parse(UnicodeString&,Formattable&,ParsePosition&)
- * fails to parse a string, it leaves the parse position unchanged.
- * The convenience method parse(UnicodeString&,Formattable&,UErrorCode&)
- * indicates parse failure by setting a failing
- * UErrorCode.
- *
- * <p><strong>Formatting</strong>
- *
- * <p>Formatting is guided by several parameters, all of which can be
- * specified either using a pattern or using the API.  The following
- * description applies to formats that do not use <a href="#sci">scientific
- * notation</a> or <a href="#sigdig">significant digits</a>.
- *
- * <ul><li>If the number of actual integer digits exceeds the
- * <em>maximum integer digits</em>, then only the least significant
- * digits are shown.  For example, 1997 is formatted as "97" if the
- * maximum integer digits is set to 2.
- *
- * <li>If the number of actual integer digits is less than the
- * <em>minimum integer digits</em>, then leading zeros are added.  For
- * example, 1997 is formatted as "01997" if the minimum integer digits
- * is set to 5.
- *
- * <li>If the number of actual fraction digits exceeds the <em>maximum
- * fraction digits</em>, then half-even rounding it performed to the
- * maximum fraction digits.  For example, 0.125 is formatted as "0.12"
- * if the maximum fraction digits is 2.  This behavior can be changed
- * by specifying a rounding increment and a rounding mode.
- *
- * <li>If the number of actual fraction digits is less than the
- * <em>minimum fraction digits</em>, then trailing zeros are added.
- * For example, 0.125 is formatted as "0.1250" if the mimimum fraction
- * digits is set to 4.
- *
- * <li>Trailing fractional zeros are not displayed if they occur
- * <em>j</em> positions after the decimal, where <em>j</em> is less
- * than the maximum fraction digits. For example, 0.10004 is
- * formatted as "0.1" if the maximum fraction digits is four or less.
- * </ul>
- *
- * <p><strong>Special Values</strong>
- *
- * <p><code>NaN</code> is represented as a single character, typically
- * <code>\\uFFFD</code>.  This character is determined by the
- * DecimalFormatSymbols object.  This is the only value for which
- * the prefixes and suffixes are not used.
- *
- * <p>Infinity is represented as a single character, typically
- * <code>\\u221E</code>, with the positive or negative prefixes and suffixes
- * applied.  The infinity character is determined by the
- * DecimalFormatSymbols object.
- *
- * <a name="sci"><strong>Scientific Notation</strong></a>
- *
- * <p>Numbers in scientific notation are expressed as the product of a mantissa
- * and a power of ten, for example, 1234 can be expressed as 1.234 x 10<sup>3</sup>. The
- * mantissa is typically in the half-open interval [1.0, 10.0) or sometimes [0.0, 1.0),
- * but it need not be.  DecimalFormat supports arbitrary mantissas.
- * DecimalFormat can be instructed to use scientific
- * notation through the API or through the pattern.  In a pattern, the exponent
- * character immediately followed by one or more digit characters indicates
- * scientific notation.  Example: "0.###E0" formats the number 1234 as
- * "1.234E3".
- *
- * <ul>
- * <li>The number of digit characters after the exponent character gives the
- * minimum exponent digit count.  There is no maximum.  Negative exponents are
- * formatted using the localized minus sign, <em>not</em> the prefix and suffix
- * from the pattern.  This allows patterns such as "0.###E0 m/s".  To prefix
- * positive exponents with a localized plus sign, specify '+' between the
- * exponent and the digits: "0.###E+0" will produce formats "1E+1", "1E+0",
- * "1E-1", etc.  (In localized patterns, use the localized plus sign rather than
- * '+'.)
- *
- * <li>The minimum number of integer digits is achieved by adjusting the
- * exponent.  Example: 0.00123 formatted with "00.###E0" yields "12.3E-4".  This
- * only happens if there is no maximum number of integer digits.  If there is a
- * maximum, then the minimum number of integer digits is fixed at one.
- *
- * <li>The maximum number of integer digits, if present, specifies the exponent
- * grouping.  The most common use of this is to generate <em>engineering
- * notation</em>, in which the exponent is a multiple of three, e.g.,
- * "##0.###E0".  The number 12345 is formatted using "##0.####E0" as "12.345E3".
- *
- * <li>When using scientific notation, the formatter controls the
- * digit counts using significant digits logic.  The maximum number of
- * significant digits limits the total number of integer and fraction
- * digits that will be shown in the mantissa; it does not affect
- * parsing.  For example, 12345 formatted with "##0.##E0" is "12.3E3".
- * See the section on significant digits for more details.
- *
- * <li>The number of significant digits shown is determined as
- * follows: If areSignificantDigitsUsed() returns false, then the
- * minimum number of significant digits shown is one, and the maximum
- * number of significant digits shown is the sum of the <em>minimum
- * integer</em> and <em>maximum fraction</em> digits, and is
- * unaffected by the maximum integer digits.  If this sum is zero,
- * then all significant digits are shown.  If
- * areSignificantDigitsUsed() returns true, then the significant digit
- * counts are specified by getMinimumSignificantDigits() and
- * getMaximumSignificantDigits().  In this case, the number of
- * integer digits is fixed at one, and there is no exponent grouping.
- *
- * <li>Exponential patterns may not contain grouping separators.
- * </ul>
- *
- * <a name="sigdig"><strong>Significant Digits</strong></a>
- *
- * <code>DecimalFormat</code> has two ways of controlling how many
- * digits are shows: (a) significant digits counts, or (b) integer and
- * fraction digit counts.  Integer and fraction digit counts are
- * described above.  When a formatter is using significant digits
- * counts, the number of integer and fraction digits is not specified
- * directly, and the formatter settings for these counts are ignored.
- * Instead, the formatter uses however many integer and fraction
- * digits are required to display the specified number of significant
- * digits.  Examples:
- *
- * <table border=0 cellspacing=3 cellpadding=0>
- *   <tr bgcolor="#ccccff">
- *     <td align=left>Pattern
- *     <td align=left>Minimum significant digits

- *     <td>1.23004
- *     <td><code>1.23</code>
- * </table>
- *
- * <ul>
- * <li>Significant digit counts may be expressed using patterns that
- * specify a minimum and maximum number of significant digits.  These
- * are indicated by the <code>'@'</code> and <code>'#'</code>
- * characters.  The minimum number of significant digits is the number
- * of <code>'@'</code> characters.  The maximum number of significant
- * digits is the number of <code>'@'</code> characters plus the number
- * of <code>'#'</code> characters following on the right.  For
- * example, the pattern <code>"@@@"</code> indicates exactly 3
- * significant digits.  The pattern <code>"@##"</code> indicates from
- * 1 to 3 significant digits.  Trailing zero digits to the right of
- * the decimal separator are suppressed after the minimum number of
- * significant digits have been shown.  For example, the pattern
- * <code>"@##"</code> formats the number 0.1203 as
- * <code>"0.12"</code>.
- *
- * <li>If a pattern uses significant digits, it may not contain a
- * decimal separator, nor the <code>'0'</code> pattern character.
- * Patterns such as <code>"@00"</code> or <code>"@.###"</code> are
- * disallowed.
- *
- * <li>Any number of <code>'#'</code> characters may be prepended to
- * the left of the leftmost <code>'@'</code> character.  These have no
- * effect on the minimum and maximum significant digits counts, but
- * may be used to position grouping separators.  For example,
- * <code>"#,#@#"</code> indicates a minimum of one significant digits,
- * a maximum of two significant digits, and a grouping size of three.
- *
- * <li>In order to enable significant digits formatting, use a pattern
- * containing the <code>'@'</code> pattern character.  Alternatively,
- * call setSignificantDigitsUsed(TRUE).
- *
- * <li>In order to disable significant digits formatting, use a
- * pattern that does not contain the <code>'@'</code> pattern
- * character. Alternatively, call setSignificantDigitsUsed(FALSE).
- *
- * <li>The number of significant digits has no effect on parsing.
- *
- * <li>Significant digits may be used together with exponential notation. Such
- * patterns are equivalent to a normal exponential pattern with a minimum and
- * maximum integer digit count of one, a minimum fraction digit count of
- * <code>getMinimumSignificantDigits() - 1</code>, and a maximum fraction digit
- * count of <code>getMaximumSignificantDigits() - 1</code>. For example, the
- * pattern <code>"@@###E0"</code> is equivalent to <code>"0.0###E0"</code>.
- *
- * <li>If signficant digits are in use, then the integer and fraction
- * digit counts, as set via the API, are ignored.  If significant
- * digits are not in use, then the signficant digit counts, as set via
- * the API, are ignored.
- *
- * </ul>
- *
- * <p><strong>Padding</strong>
- *
- * <p>DecimalFormat supports padding the result of
- * format() to a specific width.  Padding may be specified either
- * through the API or through the pattern syntax.  In a pattern the pad escape
- * character, followed by a single pad character, causes padding to be parsed
- * and formatted.  The pad escape character is '*' in unlocalized patterns, and
- * can be localized using DecimalFormatSymbols::setSymbol() with a
- * DecimalFormatSymbols::kPadEscapeSymbol
- * selector.  For example, <code>"$*x#,##0.00"</code> formats 123 to
- * <code>"$xx123.00"</code>, and 1234 to <code>"$1,234.00"</code>.
- *
- * <ul>
- * <li>When padding is in effect, the width of the positive subpattern,
- * including prefix and suffix, determines the format width.  For example, in
- * the pattern <code>"* #0 o''clock"</code>, the format width is 10.
- *
- * <li>The width is counted in 16-bit code units (UChars).
- *
- * <li>Some parameters which usually do not matter have meaning when padding is
- * used, because the pattern width is significant with padding.  In the pattern
- * "* ##,##,#,##0.##", the format width is 14.  The initial characters "##,##,"
- * do not affect the grouping size or maximum integer digits, but they do affect
- * the format width.
- *
- * <li>Padding may be inserted at one of four locations: before the prefix,
- * after the prefix, before the suffix, or after the suffix.  If padding is
- * specified in any other location, applyPattern()
- * sets a failing UErrorCode.  If there is no prefix,
- * before the prefix and after the prefix are equivalent, likewise for the
- * suffix.
- *
- * <li>When specified in a pattern, the 32-bit code point immediately
- * following the pad escape is the pad character. This may be any character,
- * including a special pattern character. That is, the pad escape
- * <em>escapes</em> the following character. If there is no character after
- * the pad escape, then the pattern is illegal.
- *
- * </ul>
- *
- * <p><strong>Rounding</strong>
- *
- * <p>DecimalFormat supports rounding to a specific increment.  For
- * example, 1230 rounded to the nearest 50 is 1250.  1.234 rounded to the
- * nearest 0.65 is 1.3.  The rounding increment may be specified through the API
- * or in a pattern.  To specify a rounding increment in a pattern, include the
- * increment in the pattern itself.  "#,#50" specifies a rounding increment of
- * 50.  "#,##0.05" specifies a rounding increment of 0.05.
- *
- * <ul>
- * <li>Rounding only affects the string produced by formatting.  It does
- * not affect parsing or change any numerical values.
- *
- * <li>A <em>rounding mode</em> determines how values are rounded; see
- * DecimalFormat::ERoundingMode.  Rounding increments specified in
- * patterns use the default mode, DecimalFormat::kRoundHalfEven.
- *
- * <li>Some locales use rounding in their currency formats to reflect the
- * smallest currency denomination.
- *
- * <li>In a pattern, digits '1' through '9' specify rounding, but otherwise
- * behave identically to digit '0'.
- * </ul>
- *
- * <p><strong>Synchronization</strong>
- *
- * <p>DecimalFormat objects are not synchronized.  Multiple
- * threads should not access one formatter concurrently.
- *
- * <p><strong>Subclassing</strong>
- *
- * <p><em>User subclasses are not supported.</em> While clients may write
- * subclasses, such code will not necessarily work and will not be
- * guaranteed to work stably from release to release.
