|
|
* 04/17/97 aliu Changed DigitCount to int per code review.
|
|
* 07/10/97 helena Made ParsePosition a class and get rid of the function
|
|
* hiding problems.
|

/**
|
|
* Concrete class for formatting decimal numbers, allowing a variety
|
|
* of parameters, and localization to Western, Arabic, or Indic numbers.
|
|
* <P>
|
|
* Normally, you get the proper NumberFormat for a specific locale
|
|
* (including the default locale) using the NumberFormat factory methods,
|
|
* rather than constructing a DecimalNumberFormat directly.
|
|
* <P>
|
|
* Either the prefixes or the suffixes must be different for the parse
|
|
* to distinguish positive from negative. Parsing will be unreliable
|
|
* if the digits, thousands or decimal separators are the same, or if
|
|
* any of them occur in the prefixes or suffixes.
|
|
* <P>
|
|
* [Special cases:]
|
|
* <P>
|
|
* NaN is formatted as a single character, typically \\uFFFD.
|
|
* <P>
|
|
* +/-Infinity is formatted as a single character, typically \\u221E,
|
|
* plus the positive and negative pre/suffixes.
|
|
* <P>
|
|
* Note: this class is designed for common users; for very large or small
|
|
* numbers, use a format that can express exponential values.
|
|
* <P>
|
|
* [Example:]
|
|
* <pre>
|
|
* . // normally we would have a GUI with a menu for this
|
|
* . long count;
|
|
* . Locale* locales = NumberFormat::getAvailableLocales(count);
|
|
*
|
|
* . double myNumber = -1234.56;
|
|
* . NumberFormat* form;
|
|
*
|
|
* . // just for fun, we print out a number with the locale number, currency
|
|
* . // and percent format for each locale we can.
|
|
* . for (int j = 0; j < 3; ++j) {
|
|
* . cout << "FORMAT" << endl;
|
|
* . for (int i = 0; i < count; ++i) {
|
|
* . if (locales[i]->getCountry().length() == 0) {
|
|
* . // skip language-only
|
|
* . continue;
|
|
* . }
|
|
* . cout << locales[i]->getDisplayName();
|
|
* . switch (j) {
|
|
* . default:
|
|
* . form = NumberFormat::getInstance(*locales[i]); break;
|
|
* . case 1:
|
|
* . form = NumberFormat::getDefaultCurrency(*locales[i]); break;
|
|
* . case 0:
|
|
* . form = NumberFormat::getDefaultPercent(*locales[i]); break;
|
|
* . }
|
|
* . UnicodeString str;
|
|
* . ErrorCode status;
|
|
* . UnicodeString pattern;
|
|
* . if (form->getDynamicClassID() == DecimalFormat::getStaticClassID())
|
|
* . ((DecimalFormat*)form)->toPattern(pattern);
|
|
* . cout << ": " << pattern
|
|
* . << " -> " << form->format(myNumber, str);
|
|
* . cout << " -> " << form->parse(form->format(myNumber, str), status)
|
|
* . << endl;
|
|
* . }
|
|
* . }
|
|
* </pre>
|
|
* [The following shows the structure of the pattern.]
|
|
* <pre>
|
|
* . pattern := subpattern{;subpattern}
|
|
* . subpattern := {prefix}integer{.fraction}{suffix}
|
|
* .
|
|
* . prefix := '\\u0000'..'\\uFFFD' - specialCharacters
|
|
* . suffix := '\\u0000'..'\\uFFFD' - specialCharacters
|
|
* . integer := '#'* '0'* '0'
|
|
* . fraction := '0'* '#'*
|
|
*
|
|
* Notation:
|
|
* . X* 0 or more instances of X
|
|
* . (X | Y) either X or Y.
|
|
* . X..Y any character from X up to Y, inclusive.
|
|
* . S - T characters in S, except those in T
|
|
* </pre>
|
|
* The first subpattern is for positive numbers. The second (optional)
|
|
* subpattern is used for negative numbers. (In both cases, ',' can
|
|
* occur inside the integer portion--it is just too messy to indicate
|
|
* in BNF.) For the second subpattern, only the PREFIX and SUFFIX are
|
|
* noted; other attributes are taken only from the first subpattern.
|
|
* <P>
|
|
* Here are the special characters used in the parts of the
|
|
* subpattern, with notes on their usage.
|
|
* <pre>
|
|
* . Symbol Meaning
|
|
* . 0 a digit, showing up a zero if it is zero
|
|
* . # a digit, supressed if zero
|
|
* . . placeholder for decimal separator
|
|
* . , placeholder for grouping separator
|
|
* . ; separates postive from negative formats
|
|
* . - default negative prefix
|
|
* . % divide by 100 and show as percentage
|
|
* . X any other characters can be used in the prefix or suffix
|
|
* . ' used to quote special characters in a prefix or suffix
|
|
* </pre>
|
|
* [Notes]
|
|
* <P>
|
|
* If there is no explicit negative subpattern, - is prefixed to the
|
|
* positive form. That is, "0.00" alone is equivalent to "0.00;-0.00".
|
|
* <P>
|
|
* Illegal formats, such as "#.#.#" in the same format, will cause a
|
|
* failing ErrorCode to be returned.
|
|
* <P>
|
|
* The grouping separator is commonly used for thousands, but in some
|
|
* countries for ten-thousands. The interval is a constant number of
|
|
* digits between the grouping characters, such as 100,000,000 or 1,0000,0000.
|
|
* If you supply a pattern with multiple grouping characters, the interval
|
|
* between the last one and the end of the integer is the one that is
|
|
* used. So "#,##,###,####" == "######,####" == "##,####,####".
|
|
* <P>
|
|
* This class only handles localized digits where the 10 digits are
|
|
* contiguous in Unicode, from 0 to 9. Other digits sets (such as
|
|
* superscripts) would need a different subclass.
