+/**
+ * The RuleBasedNumberFormat class formats numbers according to a set of rules. This number formatter is
+ * typically used for spelling out numeric values in words (e.g., 25,3476 as
+ * "twenty-five thousand three hundred seventy-six" or "vingt-cinq mille trois
+ * cents soixante-seize" or
+ * "fünfundzwanzigtausenddreihundertsechsundsiebzig"), but can also be used for
+ * other complicated formatting tasks, such as formatting a number of seconds as hours,
+ * minutes and seconds (e.g., 3,730 as "1:02:10").
+ *
+ * <p>The resources contain three predefined formatters for each locale: spellout, which
+ * spells out a value in words (123 is "one hundred twenty-three"); ordinal, which
+ * appends an ordinal suffix to the end of a numeral (123 is "123rd"); and
+ * duration, which shows a duration in seconds as hours, minutes, and seconds (123 is
+ * "2:03"). The client can also define more specialized <tt>RuleBasedNumberFormat</tt>s
+ * by supplying programmer-defined rule sets.</p>
+ *
+ * <p>The behavior of a <tt>RuleBasedNumberFormat</tt> is specified by a textual description
+ * that is either passed to the constructor as a <tt>String</tt> or loaded from a resource
+ * bundle. In its simplest form, the description consists of a semicolon-delimited list of <em>rules.</em>
+ * Each rule has a string of output text and a value or range of values it is applicable to.
+ * In a typical spellout rule set, the first twenty rules are the words for the numbers from
+ * 0 to 19:</p>
+ *
+ * <pre>zero; one; two; three; four; five; six; seven; eight; nine;
+ * ten; eleven; twelve; thirteen; fourteen; fifteen; sixteen; seventeen; eighteen; nineteen;</pre>
+ *
+ * <p>For larger numbers, we can use the preceding set of rules to format the ones place, and
+ * we only have to supply the words for the multiples of 10:</p>
+ *
+ * <pre> 20: twenty[->>];
+ * 30: thirty[->>];
+ * 40: forty[->>];
+ * 50: fifty[->>];
+ * 60: sixty[->>];
+ * 70: seventy[->>];
+ * 80: eighty[->>];
+ * 90: ninety[->>];</pre>
+ *
+ * <p>In these rules, the <em>base value</em> is spelled out explicitly and set off from the
+ * rule's output text with a colon. The rules are in a sorted list, and a rule is applicable
+ * to all numbers from its own base value to one less than the next rule's base value. The
+ * ">>" token is called a <em>substitution</em> and tells the fomatter to
+ * isolate the number's ones digit, format it using this same set of rules, and place the
+ * result at the position of the ">>" token. Text in brackets is omitted if
+ * the number being formatted is an even multiple of 10 (the hyphen is a literal hyphen; 24
+ * is "twenty-four," not "twenty four").</p>
+ *
+ * <p>For even larger numbers, we can actually look up several parts of the number in the
+ * list:</p>
+ *
+ * <pre>100: << hundred[ >>];</pre>
+ *
+ * <p>The "<<" represents a new kind of substitution. The << isolates
+ * the hundreds digit (and any digits to its left), formats it using this same rule set, and
+ * places the result where the "<<" was. Notice also that the meaning of
+ * >> has changed: it now refers to both the tens and the ones digits. The meaning of
+ * both substitutions depends on the rule's base value. The base value determines the rule's <em>divisor,</em>
+ * which is the highest power of 10 that is less than or equal to the base value (the user
+ * can change this). To fill in the substitutions, the formatter divides the number being
+ * formatted by the divisor. The integral quotient is used to fill in the <<
+ * substitution, and the remainder is used to fill in the >> substitution. The meaning
+ * of the brackets changes similarly: text in brackets is omitted if the value being
+ * formatted is an even multiple of the rule's divisor. The rules are applied recursively, so
+ * if a substitution is filled in with text that includes another substitution, that
+ * substitution is also filled in.</p>
+ *
+ * <p>This rule covers values up to 999, at which point we add another rule:</p>
+ *
+ * <pre>1000: << thousand[ >>];</pre>
+ *
+ * <p>Again, the meanings of the brackets and substitution tokens shift because the rule's
+ * base value is a higher power of 10, changing the rule's divisor. This rule can actually be
+ * used all the way up to 999,999. This allows us to finish out the rules as follows:</p>
+ *
+ * <pre> 1,000,000: << million[ >>];
+ * 1,000,000,000: << billion[ >>];
+ * 1,000,000,000,000: << trillion[ >>];
+ * 1,000,000,000,000,000: OUT OF RANGE!;</pre>
+ *
+ * <p>Commas, periods, and spaces can be used in the base values to improve legibility and
+ * are ignored by the rule parser. The last rule in the list is customarily treated as an
+ * "overflow rule," applying to everything from its base value on up, and often (as
+ * in this example) being used to print out an error message or default representation.
+ * Notice also that the size of the major groupings in large numbers is controlled by the
+ * spacing of the rules: because in English we group numbers by thousand, the higher rules
+ * are separated from each other by a factor of 1,000.</p>
+ *
+ * <p>To see how these rules actually work in practice, consider the following example:
+ * Formatting 25,430 with this rule set would work like this:</p>
+ *
+ * <table border="0" width="100%">
+ * <tr>
+ * <td><strong><< thousand >></strong></td>
+ * <td>[the rule whose base value is 1,000 is applicable to 25,340]</td>
+ * </tr>
+ * <tr>
+ * <td><strong>twenty->></strong> thousand >></td>
+ * <td>[25,340 over 1,000 is 25. The rule for 20 applies.]</td>
+ * </tr>
+ * <tr>
+ * <td>twenty-<strong>five</strong> thousand >></td>
+ * <td>[25 mod 10 is 5. The rule for 5 is "five."</td>
+ * </tr>
+ * <tr>
+ * <td>twenty-five thousand <strong><< hundred >></strong></td>
+ * <td>[25,340 mod 1,000 is 340. The rule for 100 applies.]</td>
+ * </tr>
+ * <tr>
+ * <td>twenty-five thousand <strong>three</strong> hundred >></td>
+ * <td>[340 over 100 is 3. The rule for 3 is "three."]</td>
+ * </tr>
+ * <tr>
+ * <td>twenty-five thousand three hundred <strong>forty</strong></td>
+ * <td>[340 mod 100 is 40. The rule for 40 applies. Since 40 divides
+ * evenly by 10, the hyphen and substitution in the brackets are omitted.]</td>
+ * </tr>
+ * </table>
+ *
+ * <p>The above syntax suffices only to format positive integers. To format negative numbers,
+ * we add a special rule:</p>
+ *
+ * <pre>-x: minus >>;</pre>
+ *
+ * <p>This is called a <em>negative-number rule,</em> and is identified by "-x"
+ * where the base value would be. This rule is used to format all negative numbers. the
+ * >> token here means "find the number's absolute value, format it with these
+ * rules, and put the result here."</p>
+ *
+ * <p>We also add a special rule called a <em>fraction rule </em>for numbers with fractional
+ * parts:</p>
+ *
+ * <pre>x.x: << point >>;</pre>
+ *
+ * <p>This rule is used for all positive non-integers (negative non-integers pass through the
+ * negative-number rule first and then through this rule). Here, the << token refers to
+ * the number's integral part, and the >> to the number's fractional part. The
+ * fractional part is formatted as a series of single-digit numbers (e.g., 123.456 would be
+ * formatted as "one hundred twenty-three point four five six").</p>
+ *
+ * <p>To see how this rule syntax is applied to various languages, examine the resource data.</p>
+ *
+ * <p>There is actually much more flexibility built into the rule language than the
+ * description above shows. A formatter may own multiple rule sets, which can be selected by
+ * the caller, and which can use each other to fill in their substitutions. Substitutions can
+ * also be filled in with digits, using a DecimalFormat object. There is syntax that can be
+ * used to alter a rule's divisor in various ways. And there is provision for much more
+ * flexible fraction handling. A complete description of the rule syntax follows:</p>
+ *
+ * <hr>
+ *
+ * <p>The description of a <tt>RuleBasedNumberFormat</tt>'s behavior consists of one or more <em>rule
+ * sets.</em> Each rule set consists of a name, a colon, and a list of <em>rules.</em> A rule
+ * set name must begin with a % sign. Rule sets with names that begin with a single % sign
+ * are <em>public:</em> the caller can specify that they be used to format and parse numbers.
+ * Rule sets with names that begin with %% are <em>private:</em> they exist only for the use
+ * of other rule sets. If a formatter only has one rule set, the name may be omitted.</p>
+ *
+ * <p>The user can also specify a special "rule set" named <tt>%%lenient-parse</tt>.
+ * The body of <tt>%%lenient-parse</tt> isn't a set of number-formatting rules, but a <tt>RuleBasedCollator</tt>
+ * description which is used to define equivalences for lenient parsing. For more information
+ * on the syntax, see <tt>RuleBasedCollator</tt>. For more information on lenient parsing,
+ * see <tt>setLenientParse()</tt>. <em>Note:</em> symbols that have syntactic meaning
+ * in collation rules, such as '&', have no particular meaning when appearing outside
+ * of the <tt>lenient-parse</tt> rule set.</p>
+ *
+ * <p>The body of a rule set consists of an ordered, semicolon-delimited list of <em>rules.</em>
+ * Internally, every rule has a base value, a divisor, rule text, and zero, one, or two <em>substitutions.</em>
+ * These parameters are controlled by the description syntax, which consists of a <em>rule
+ * descriptor,</em> a colon, and a <em>rule body.</em></p>
+ *
+ * <p>A rule descriptor can take one of the following forms (text in <em>italics</em> is the
+ * name of a token):</p>
+ *
+ * <table border="0" width="100%">
+ * <tr>
+ * <td><em>bv</em>:</td>
+ * <td><em>bv</em> specifies the rule's base value. <em>bv</em> is a decimal
+ * number expressed using ASCII digits. <em>bv</em> may contain spaces, period, and commas,
+ * which are ignored. The rule's divisor is the highest power of 10 less than or equal to
+ * the base value.</td>
+ * </tr>
+ * <tr>
+ * <td><em>bv</em>/<em>rad</em>:</td>
+ * <td><em>bv</em> specifies the rule's base value. The rule's divisor is the
+ * highest power of <em>rad</em> less than or equal to the base value.</td>
+ * </tr>
+ * <tr>
+ * <td><em>bv</em>>:</td>
+ * <td><em>bv</em> specifies the rule's base value. To calculate the divisor,
+ * let the radix be 10, and the exponent be the highest exponent of the radix that yields a
+ * result less than or equal to the base value. Every > character after the base value
+ * decreases the exponent by 1. If the exponent is positive or 0, the divisor is the radix
+ * raised to the power of the exponent; otherwise, the divisor is 1.</td>

+ *
+ * <p>A rule set may be either a regular rule set or a <em>fraction rule set,</em> depending
+ * on whether it is used to format a number's integral part (or the whole number) or a
+ * number's fractional part. Using a rule set to format a rule's fractional part makes it a
+ * fraction rule set.</p>
+ *
+ * <p>Which rule is used to format a number is defined according to one of the following
+ * algorithms: If the rule set is a regular rule set, do the following:
+ *
+ * <ul>
+ * <li>If the rule set includes a master rule (and the number was passed in as a <tt>double</tt>),
+ * use the master rule. (If the number being formatted was passed in as a <tt>long</tt>,
+ * the master rule is ignored.)</li>
+ * <li>If the number is negative, use the negative-number rule.</li>
+ * <li>If the number has a fractional part and is greater than 1, use the improper fraction
+ * rule.</li>
+ * <li>If the number has a fractional part and is between 0 and 1, use the proper fraction
+ * rule.</li>
+ * <li>Binary-search the rule list for the rule with the highest base value less than or equal
+ * to the number. If that rule has two substitutions, its base value is not an even multiple
+ * of its divisor, and the number <em>is</em> an even multiple of the rule's divisor, use the
+ * rule that precedes it in the rule list. Otherwise, use the rule itself.</li>
+ * </ul>
+ *
+ * <p>If the rule set is a fraction rule set, do the following:
+ *
+ * <ul>
+ * <li>Ignore negative-number and fraction rules.</li>
+ * <li>For each rule in the list, multiply the number being formatted (which will always be
+ * between 0 and 1) by the rule's base value. Keep track of the distance between the result
+ * the nearest integer.</li>
+ * <li>Use the rule that produced the result closest to zero in the above calculation. In the
+ * event of a tie or a direct hit, use the first matching rule encountered. (The idea here is
+ * to try each rule's base value as a possible denominator of a fraction. Whichever
+ * denominator produces the fraction closest in value to the number being formatted wins.) If
+ * the rule following the matching rule has the same base value, use it if the numerator of
+ * the fraction is anything other than 1; if the numerator is 1, use the original matching
+ * rule. (This is to allow singular and plural forms of the rule text without a lot of extra
+ * hassle.)</li>
+ * </ul>
+ *
+ * <p>A rule's body consists of a string of characters terminated by a semicolon. The rule
+ * may include zero, one, or two <em>substitution tokens,</em> and a range of text in
+ * brackets. The brackets denote optional text (and may also include one or both
+ * substitutions). The exact meanings of the substitution tokens, and under what conditions
+ * optional text is omitted, depend on the syntax of the substitution token and the context.
+ * The rest of the text in a rule body is literal text that is output when the rule matches
+ * the number being formatted.</p>
+ *
+ * <p>A substitution token begins and ends with a <em>token character.</em> The token
+ * character and the context together specify a mathematical operation to be performed on the
+ * number being formatted. An optional <em>substitution descriptor </em>specifies how the
+ * value resulting from that operation is used to fill in the substitution. The position of
+ * the substitution token in the rule body specifies the location of the resultant text in
+ * the original rule text.</p>
+ *
+ * <p>The meanings of the substitution token characters are as follows:</p>
+ *
+ * <table border="0" width="100%">

+ * </table>
+ *
+ * <p>Whitespace is ignored between a rule set name and a rule set body, between a rule
+ * descriptor and a rule body, or between rules. If a rule body begins with an apostrophe,
+ * the apostrophe is ignored, but all text after it becomes significant (this is how you can
+ * have a rule's rule text begin with whitespace). There is no escape function: the semicolon
+ * is not allowed in rule set names or in rule text, and the colon is not allowed in rule set
+ * names. The characters beginning a substitution token are always treated as the beginning

+ * Localization data is represented as a textual description. The description represents
+ * an array of arrays of string. The first element is an array of the public rule set names,
+ * each of these must be one of the public rule set names that appear in the rules. Only
+ * names in this array will be treated as public rule set names by the API. Each subsequent
+ * element is an array of localizations of these names. The first element of one of these
+ * subarrays is the locale name, and the remaining elements are localizations of the
+ * public rule set names, in the same order as they were listed in the first arrray.</p>
+ * <p>In the syntax, angle brackets '<', '>' are used to delimit the arrays, and comma ',' is used
+ * to separate elements of an array. Whitespace is ignored, unless quoted.</p>
