69 : * The RuleBasedNumberFormat class formats numbers according to a set of rules. This number formatter is
70 : * typically used for spelling out numeric values in words (e.g., 25,3476 as
71 : * "twenty-five thousand three hundred seventy-six" or "vingt-cinq mille trois
72 : * cents soixante-seize" or
73 : * "fünfundzwanzigtausenddreihundertsechsundsiebzig"), but can also be used for
74 : * other complicated formatting tasks, such as formatting a number of seconds as hours,
75 : * minutes and seconds (e.g., 3,730 as "1:02:10").
76 : *
77 : * <p>The resources contain three predefined formatters for each locale: spellout, which
78 : * spells out a value in words (123 is "one hundred twenty-three"); ordinal, which
79 : * appends an ordinal suffix to the end of a numeral (123 is "123rd"); and
80 : * duration, which shows a duration in seconds as hours, minutes, and seconds (123 is
81 : * "2:03"). The client can also define more specialized <tt>RuleBasedNumberFormat</tt>s
82 : * by supplying programmer-defined rule sets.</p>
83 : *
84 : * <p>The behavior of a <tt>RuleBasedNumberFormat</tt> is specified by a textual description
85 : * that is either passed to the constructor as a <tt>String</tt> or loaded from a resource
86 : * bundle. In its simplest form, the description consists of a semicolon-delimited list of <em>rules.</em>
87 : * Each rule has a string of output text and a value or range of values it is applicable to.
88 : * In a typical spellout rule set, the first twenty rules are the words for the numbers from
89 : * 0 to 19:</p>
90 : *
91 : * <pre>zero; one; two; three; four; five; six; seven; eight; nine;
92 : * ten; eleven; twelve; thirteen; fourteen; fifteen; sixteen; seventeen; eighteen; nineteen;</pre>
93 : *
94 : * <p>For larger numbers, we can use the preceding set of rules to format the ones place, and
95 : * we only have to supply the words for the multiples of 10:</p>
96 : *
97 : * <pre> 20: twenty[->>];
98 : * 30: thirty[->>];
99 : * 40: forty[->>];
100 : * 50: fifty[->>];
101 : * 60: sixty[->>];
102 : * 70: seventy[->>];
103 : * 80: eighty[->>];
104 : * 90: ninety[->>];</pre>
105 : *
106 : * <p>In these rules, the <em>base value</em> is spelled out explicitly and set off from the
107 : * rule's output text with a colon. The rules are in a sorted list, and a rule is applicable
108 : * to all numbers from its own base value to one less than the next rule's base value. The
109 : * ">>" token is called a <em>substitution</em> and tells the fomatter to
110 : * isolate the number's ones digit, format it using this same set of rules, and place the
111 : * result at the position of the ">>" token. Text in brackets is omitted if
112 : * the number being formatted is an even multiple of 10 (the hyphen is a literal hyphen; 24
113 : * is "twenty-four," not "twenty four").</p>
114 : *
115 : * <p>For even larger numbers, we can actually look up several parts of the number in the
116 : * list:</p>
117 : *
118 : * <pre>100: << hundred[ >>];</pre>
119 : *
120 : * <p>The "<<" represents a new kind of substitution. The << isolates
121 : * the hundreds digit (and any digits to its left), formats it using this same rule set, and
122 : * places the result where the "<<" was. Notice also that the meaning of
123 : * >> has changed: it now refers to both the tens and the ones digits. The meaning of
124 : * both substitutions depends on the rule's base value. The base value determines the rule's <em>divisor,</em>
125 : * which is the highest power of 10 that is less than or equal to the base value (the user
126 : * can change this). To fill in the substitutions, the formatter divides the number being
127 : * formatted by the divisor. The integral quotient is used to fill in the <<
128 : * substitution, and the remainder is used to fill in the >> substitution. The meaning
129 : * of the brackets changes similarly: text in brackets is omitted if the value being
130 : * formatted is an even multiple of the rule's divisor. The rules are applied recursively, so
131 : * if a substitution is filled in with text that includes another substitution, that
132 : * substitution is also filled in.</p>
133 : *
134 : * <p>This rule covers values up to 999, at which point we add another rule:</p>
135 : *
136 : * <pre>1000: << thousand[ >>];</pre>
137 : *
138 : * <p>Again, the meanings of the brackets and substitution tokens shift because the rule's
139 : * base value is a higher power of 10, changing the rule's divisor. This rule can actually be
140 : * used all the way up to 999,999. This allows us to finish out the rules as follows:</p>
141 : *
142 : * <pre> 1,000,000: << million[ >>];
143 : * 1,000,000,000: << billion[ >>];
144 : * 1,000,000,000,000: << trillion[ >>];
145 : * 1,000,000,000,000,000: OUT OF RANGE!;</pre>
146 : *
147 : * <p>Commas, periods, and spaces can be used in the base values to improve legibility and
148 : * are ignored by the rule parser. The last rule in the list is customarily treated as an
149 : * "overflow rule," applying to everything from its base value on up, and often (as
150 : * in this example) being used to print out an error message or default representation.
151 : * Notice also that the size of the major groupings in large numbers is controlled by the
152 : * spacing of the rules: because in English we group numbers by thousand, the higher rules
153 : * are separated from each other by a factor of 1,000.</p>
154 : *
155 : * <p>To see how these rules actually work in practice, consider the following example:
156 : * Formatting 25,430 with this rule set would work like this:</p>
157 : *
158 : * <table border="0" width="100%">
159 : * <tr>
160 : * <td><strong><< thousand >></strong></td>
161 : * <td>[the rule whose base value is 1,000 is applicable to 25,340]</td>
162 : * </tr>
163 : * <tr>
164 : * <td><strong>twenty->></strong> thousand >></td>
165 : * <td>[25,340 over 1,000 is 25. The rule for 20 applies.]</td>
166 : * </tr>
167 : * <tr>
168 : * <td>twenty-<strong>five</strong> thousand >></td>
169 : * <td>[25 mod 10 is 5. The rule for 5 is "five."</td>
170 : * </tr>
171 : * <tr>
172 : * <td>twenty-five thousand <strong><< hundred >></strong></td>
173 : * <td>[25,340 mod 1,000 is 340. The rule for 100 applies.]</td>
174 : * </tr>
175 : * <tr>
176 : * <td>twenty-five thousand <strong>three</strong> hundred >></td>
177 : * <td>[340 over 100 is 3. The rule for 3 is "three."]</td>
178 : * </tr>
179 : * <tr>
180 : * <td>twenty-five thousand three hundred <strong>forty</strong></td>
181 : * <td>[340 mod 100 is 40. The rule for 40 applies. Since 40 divides
182 : * evenly by 10, the hyphen and substitution in the brackets are omitted.]</td>
183 : * </tr>
184 : * </table>
185 : *
186 : * <p>The above syntax suffices only to format positive integers. To format negative numbers,
187 : * we add a special rule:</p>
188 : *
189 : * <pre>-x: minus >>;</pre>
190 : *
191 : * <p>This is called a <em>negative-number rule,</em> and is identified by "-x"
192 : * where the base value would be. This rule is used to format all negative numbers. the
193 : * >> token here means "find the number's absolute value, format it with these
194 : * rules, and put the result here."</p>
195 : *
196 : * <p>We also add a special rule called a <em>fraction rule </em>for numbers with fractional
197 : * parts:</p>
198 : *
199 : * <pre>x.x: << point >>;</pre>
200 : *
201 : * <p>This rule is used for all positive non-integers (negative non-integers pass through the
202 : * negative-number rule first and then through this rule). Here, the << token refers to
203 : * the number's integral part, and the >> to the number's fractional part. The
204 : * fractional part is formatted as a series of single-digit numbers (e.g., 123.456 would be
205 : * formatted as "one hundred twenty-three point four five six").</p>
206 : *
207 : * <p>To see how this rule syntax is applied to various languages, examine the resource data.</p>
208 : *
209 : * <p>There is actually much more flexibility built into the rule language than the
210 : * description above shows. A formatter may own multiple rule sets, which can be selected by
211 : * the caller, and which can use each other to fill in their substitutions. Substitutions can
212 : * also be filled in with digits, using a DecimalFormat object. There is syntax that can be
213 : * used to alter a rule's divisor in various ways. And there is provision for much more
214 : * flexible fraction handling. A complete description of the rule syntax follows:</p>
215 : *
216 : * <hr>
217 : *
218 : * <p>The description of a <tt>RuleBasedNumberFormat</tt>'s behavior consists of one or more <em>rule
219 : * sets.</em> Each rule set consists of a name, a colon, and a list of <em>rules.</em> A rule
220 : * set name must begin with a % sign. Rule sets with names that begin with a single % sign
221 : * are <em>public:</em> the caller can specify that they be used to format and parse numbers.
222 : * Rule sets with names that begin with %% are <em>private:</em> they exist only for the use
223 : * of other rule sets. If a formatter only has one rule set, the name may be omitted.</p>
224 : *
225 : * <p>The user can also specify a special "rule set" named <tt>%%lenient-parse</tt>.
226 : * The body of <tt>%%lenient-parse</tt> isn't a set of number-formatting rules, but a <tt>RuleBasedCollator</tt>
227 : * description which is used to define equivalences for lenient parsing. For more information
228 : * on the syntax, see <tt>RuleBasedCollator</tt>. For more information on lenient parsing,
229 : * see <tt>setLenientParse()</tt>. <em>Note:</em> symbols that have syntactic meaning
230 : * in collation rules, such as '&', have no particular meaning when appearing outside
231 : * of the <tt>lenient-parse</tt> rule set.</p>
232 : *
233 : * <p>The body of a rule set consists of an ordered, semicolon-delimited list of <em>rules.</em>
234 : * Internally, every rule has a base value, a divisor, rule text, and zero, one, or two <em>substitutions.</em>
235 : * These parameters are controlled by the description syntax, which consists of a <em>rule
236 : * descriptor,</em> a colon, and a <em>rule body.</em></p>
237 : *
238 : * <p>A rule descriptor can take one of the following forms (text in <em>italics</em> is the
239 : * name of a token):</p>
240 : *
241 : * <table border="0" width="100%">

324 : *
325 : * <p>A rule set may be either a regular rule set or a <em>fraction rule set,</em> depending
326 : * on whether it is used to format a number's integral part (or the whole number) or a
327 : * number's fractional part. Using a rule set to format a rule's fractional part makes it a
328 : * fraction rule set.</p>
329 : *
330 : * <p>Which rule is used to format a number is defined according to one of the following
331 : * algorithms: If the rule set is a regular rule set, do the following:
332 : *
333 : * <ul>
334 : * <li>If the rule set includes a master rule (and the number was passed in as a <tt>double</tt>),
335 : * use the master rule. (If the number being formatted was passed in as a <tt>long</tt>,
336 : * the master rule is ignored.)</li>
337 : * <li>If the number is negative, use the negative-number rule.</li>
338 : * <li>If the number has a fractional part and is greater than 1, use the improper fraction
339 : * rule.</li>
340 : * <li>If the number has a fractional part and is between 0 and 1, use the proper fraction
341 : * rule.</li>
342 : * <li>Binary-search the rule list for the rule with the highest base value less than or equal
343 : * to the number. If that rule has two substitutions, its base value is not an even multiple
344 : * of its divisor, and the number <em>is</em> an even multiple of the rule's divisor, use the
345 : * rule that precedes it in the rule list. Otherwise, use the rule itself.</li>
346 : * </ul>
347 : *
348 : * <p>If the rule set is a fraction rule set, do the following:
349 : *
350 : * <ul>
351 : * <li>Ignore negative-number and fraction rules.</li>
352 : * <li>For each rule in the list, multiply the number being formatted (which will always be
353 : * between 0 and 1) by the rule's base value. Keep track of the distance between the result
354 : * the nearest integer.</li>
355 : * <li>Use the rule that produced the result closest to zero in the above calculation. In the
356 : * event of a tie or a direct hit, use the first matching rule encountered. (The idea here is
357 : * to try each rule's base value as a possible denominator of a fraction. Whichever
358 : * denominator produces the fraction closest in value to the number being formatted wins.) If
359 : * the rule following the matching rule has the same base value, use it if the numerator of
360 : * the fraction is anything other than 1; if the numerator is 1, use the original matching
361 : * rule. (This is to allow singular and plural forms of the rule text without a lot of extra
362 : * hassle.)</li>
363 : * </ul>
364 : *
365 : * <p>A rule's body consists of a string of characters terminated by a semicolon. The rule
366 : * may include zero, one, or two <em>substitution tokens,</em> and a range of text in
367 : * brackets. The brackets denote optional text (and may also include one or both
368 : * substitutions). The exact meanings of the substitution tokens, and under what conditions
369 : * optional text is omitted, depend on the syntax of the substitution token and the context.
370 : * The rest of the text in a rule body is literal text that is output when the rule matches
371 : * the number being formatted.</p>
372 : *
373 : * <p>A substitution token begins and ends with a <em>token character.</em> The token
374 : * character and the context together specify a mathematical operation to be performed on the
375 : * number being formatted. An optional <em>substitution descriptor </em>specifies how the
376 : * value resulting from that operation is used to fill in the substitution. The position of
377 : * the substitution token in the rule body specifies the location of the resultant text in
378 : * the original rule text.</p>
379 : *

536 : * <p><b>Localizations</b></p>
537 : * <p>Constructors are available that allow the specification of localizations for the
538 : * public rule sets (and also allow more control over what public rule sets are available).
539 : * Localization data is represented as a textual description. The description represents
540 : * an array of arrays of string. The first element is an array of the public rule set names,
541 : * each of these must be one of the public rule set names that appear in the rules. Only
542 : * names in this array will be treated as public rule set names by the API. Each subsequent
543 : * element is an array of localizations of these names. The first element of one of these
544 : * subarrays is the locale name, and the remaining elements are localizations of the
545 : * public rule set names, in the same order as they were listed in the first arrray.</p>
546 : * <p>In the syntax, angle brackets '<', '>' are used to delimit the arrays, and comma ',' is used
547 : * to separate elements of an array. Whitespace is ignored, unless quoted.</p>
548 : * <p>For example:<pre>
549 : * < < %foo, %bar, %baz >,
550 : * < en, Foo, Bar, Baz >,
