A class that 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 * "funfundzwanzigtausenddreihundertsechsundsiebzig"), 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").
* *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 RuleBasedNumberFormats * by supplying programmer-defined rule sets.
* *The behavior of a RuleBasedNumberFormat is specified by a textual description * that is either passed to the constructor as a String or loaded from a resource * bundle. In its simplest form, the description consists of a semicolon-delimited list of rules. * 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:
* *zero; one; two; three; four; five; six; seven; eight; nine; * ten; eleven; twelve; thirteen; fourteen; fifteen; sixteen; seventeen; eighteen; nineteen;* *
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:
* *20: twenty[->>];
* 30: thirty{->>];
* 40: forty[->>];
* 50: fifty[->>];
* 60: sixty[->>];
* 70: seventy[->>];
* 80: eighty[->>];
* 90: ninety[->>];
*
* In these rules, the base value 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 substitution and tells the formatter 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").
* *For even larger numbers, we can actually look up several parts of the number in the * list:
* *100: << hundred[ >>];* *
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 divisor, * 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.
* *This rule covers values up to 999, at which point we add another rule:
* *1000: << thousand[ >>];* *
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:
* *1,000,000: << million[ >>]; * 1,000,000,000: << billion[ >>]; * 1,000,000,000,000: << trillion[ >>]; * 1,000,000,000,000,000: OUT OF RANGE!;* *
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.
* *To see how these rules actually work in practice, consider the following example: * Formatting 25,430 with this rule set would work like this:
* *| * | << thousand >> | *[the rule whose base value is 1,000 is applicable to 25,340] | *
| * | twenty->> thousand >> | *[25,340 over 1,000 is 25. The rule for 20 applies.] | *
| * | twenty-five thousand >> | *[25 mod 10 is 5. The rule for 5 is "five." | *
| * | twenty-five thousand << hundred >> | *[25,340 mod 1,000 is 340. The rule for 100 applies.] | *
| * | twenty-five thousand three hundred >> | *[340 over 100 is 3. The rule for 3 is "three."] | *
| * | twenty-five thousand three hundred forty | *[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.] | *
The above syntax suffices only to format positive integers. To format negative numbers, * we add a special rule:
* *-x: minus >>;* *
This is called a negative-number rule, 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."
* *We also add a special rule called a fraction rule for numbers with fractional * parts:
* *x.x: << point >>;* *
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").
* *To see how this rule syntax is applied to various languages, examine the resource data.
* *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:
* *The description of a RuleBasedNumberFormat's behavior consists of one or more rule * sets. Each rule set consists of a name, a colon, and a list of rules. A rule * set name must begin with a % sign. Rule sets with names that begin with a single % sign * are public: the caller can specify that they be used to format and parse numbers. * Rule sets with names that begin with %% are private: they exist only for the use * of other rule sets. If a formatter only has one rule set, the name may be omitted.
* *The user can also specify a special "rule set" named %%lenient-parse. * The body of %%lenient-parse isn't a set of number-formatting rules, but a RuleBasedCollator * description which is used to define equivalences for lenient parsing. For more information * on the syntax, see RuleBasedCollator. For more information on lenient parsing, * see setLenientParse(). Note: symbols that have syntactic meaning * in collation rules, such as '&', have no particular meaning when appearing outside * of the lenient-parse rule set.
* *The body of a rule set consists of an ordered, semicolon-delimited list of rules. * Internally, every rule has a base value, a divisor, rule text, and zero, one, or two substitutions. * These parameters are controlled by the description syntax, which consists of a rule * descriptor, a colon, and a rule body.
* *A rule descriptor can take one of the following forms (text in italics is the * name of a token):
* *| * | bv: | *bv specifies the rule's base value. bv is a decimal * number expressed using ASCII digits. bv 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. | *
| * | bv/rad: | *bv specifies the rule's base value. The rule's divisor is the * highest power of rad less than or equal to the base value. | *
| * | bv>: | *bv 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. | *
| * | bv/rad>: | *bv specifies the rule's base value. To calculate the divisor, * let the radix be rad, 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 radix * 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. | *
| * | -x: | *The rule is a negative-number rule. | *
| * | x.x: | *The rule is an improper fraction rule. If the full stop in * the middle of the rule name is replaced with the decimal point * that is used in the language or DecimalFormatSymbols, then that rule will * have precedence when formatting and parsing this rule. For example, some * languages use the comma, and can thus be written as x,x instead. For example, * you can use "x.x: << point >>;x,x: << comma >>;" to * handle the decimal point that matches the language's natural spelling of * the punctuation of either the full stop or comma. | *
| * | 0.x: | *The rule is a proper fraction rule. If the full stop in * the middle of the rule name is replaced with the decimal point * that is used in the language or DecimalFormatSymbols, then that rule will * have precedence when formatting and parsing this rule. For example, some * languages use the comma, and can thus be written as 0,x instead. For example, * you can use "0.x: point >>;0,x: comma >>;" to * handle the decimal point that matches the language's natural spelling of * the punctuation of either the full stop or comma | *
| * | x.0: | *The rule is a default rule. If the full stop in * the middle of the rule name is replaced with the decimal point * that is used in the language or DecimalFormatSymbols, then that rule will * have precedence when formatting and parsing this rule. For example, some * languages use the comma, and can thus be written as x,0 instead. For example, * you can use "x.0: << point;x,0: << comma;" to * handle the decimal point that matches the language's natural spelling of * the punctuation of either the full stop or comma | *
| * | Inf: | *The rule for infinity. | *
| * | NaN: | *The rule for an IEEE 754 NaN (not a number). | *
| * | nothing | *If the rule's rule descriptor is left out, the base value is one plus the * preceding rule's base value (or zero if this is the first rule in the list) in a normal * rule set. In a fraction rule set, the base value is the same as the preceding rule's * base value. | *
A rule set may be either a regular rule set or a fraction rule set, 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.
* *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: * *
If the rule set is a fraction rule set, do the following: * *
A rule's body consists of a string of characters terminated by a semicolon. The rule * may include zero, one, or two substitution tokens, 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.
* *A substitution token begins and ends with a token character. The token * character and the context together specify a mathematical operation to be performed on the * number being formatted. An optional substitution descriptor 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.
* *The meanings of the substitution token characters are as follows:
* *| * | >> | *in normal rule | *Divide the number by the rule's divisor and format the remainder | *
| * | * | in negative-number rule | *Find the absolute value of the number and format the result | *
| * | * | in fraction or default rule | *Isolate the number's fractional part and format it. | *
| * | * | in rule in fraction rule set | *Not allowed. | *
| * | >>> | *in normal rule | *Divide the number by the rule's divisor and format the remainder, * but bypass the normal rule-selection process and just use the * rule that precedes this one in this rule list. | *
| * | * | in all other rules | *Not allowed. | *
| * | << | *in normal rule | *Divide the number by the rule's divisor, perform floor() on the quotient,
* and format the resulting value. * If there is a DecimalFormat pattern between the < characters and the * rule does NOT also contain a >> substitution, we DON'T perform * floor() on the quotient-- the quotient is passed through to the DecimalFormat * intact. That is, for the value 1,900: * - "1/1000: << thousand;" will produce "one thousand" * - "1/1000: <0< thousand;" will produce "2 thousand" (NOT "1 thousand") * - "1/1000: <0< seconds >0> milliseconds;" will produce "1 second 900 milliseconds" * |
*
| * | * | in negative-number rule | *Not allowed. | *
| * | * | in fraction or default rule | *Isolate the number's integral part and format it. | *
| * | * | in rule in fraction rule set | *Multiply the number by the rule's base value and format the result. | *
| * | == | *in all rule sets | *Format the number unchanged | *
| * | [] | *in normal rule | *Omit the optional text if the number is an even multiple of the rule's divisor | *
| * | * | in negative-number rule | *Not allowed. | *
| * | * | in improper-fraction rule | *Omit the optional text if the number is between 0 and 1 (same as specifying both an * x.x rule and a 0.x rule) | *
| * | * | in default rule | *Omit the optional text if the number is an integer (same as specifying both an x.x * rule and an x.0 rule) | *
| * | * | in proper-fraction rule | *Not allowed. | *
| * | * | in rule in fraction rule set | *Omit the optional text if multiplying the number by the rule's base value yields 1. | *
| $(cardinal,plural syntax)$ | ** | in all rule sets | *This provides the ability to choose a word based on the number divided by the radix to the power of the * exponent of the base value for the specified locale, which is normally equivalent to the << value. * This uses the cardinal plural rules from PluralFormat. All strings used in the plural format are treated * as the same base value for parsing. | *
| $(ordinal,plural syntax)$ | ** | in all rule sets | *This provides the ability to choose a word based on the number divided by the radix to the power of the * exponent of the base value for the specified locale, which is normally equivalent to the << value. * This uses the ordinal plural rules from PluralFormat. All strings used in the plural format are treated * as the same base value for parsing. | *
The substitution descriptor (i.e., the text between the token characters) may take one * of three forms:
* *| * | a rule set name | *Perform the mathematical operation on the number, and format the result using the * named rule set. | *
| * | a DecimalFormat pattern | *Perform the mathematical operation on the number, and format the result using a * DecimalFormat with the specified pattern. The pattern must begin with 0 or #. | *
| * | nothing | *Perform the mathematical operation on the number, and format the result using the rule
* set containing the current rule, except:
|
*
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 * of a substitution token.
* *See the resource data and the demo program for annotated examples of real rule sets * using these features.
