DecimalFormatis a concrete subclass of *NumberFormatthat 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, and Indic digits. It also * supports different kinds of numbers, including integers (123), fixed-point * numbers (123.4), scientific notation (1.23E4), percentages (12%), and * currency amounts ($123). All of these can be localized. * *To obtain a
NumberFormatfor a specific locale, including the * default locale, call one ofNumberFormat's factory methods, such * asgetInstance(). In general, do not call the *DecimalFormatconstructors directly, since the *NumberFormatfactory methods may return subclasses other than *DecimalFormat. If you need to customize the format object, do * something like this: * ** ** NumberFormat f = NumberFormat.getInstance(loc); * if (f instanceof DecimalFormat) { * ((DecimalFormat) f).setDecimalSeparatorAlwaysShown(true); * } *A
DecimalFormatcomprises a pattern and a set of * symbols. The pattern may be set directly using *applyPattern(), or indirectly using the API methods. The * symbols are stored in aDecimalFormatSymbolsobject. When using * theNumberFormatfactory methods, the pattern and symbols are * read from localizedResourceBundles. * *Patterns
* *DecimalFormatpatterns have the following syntax: ** ** Pattern: * PositivePattern * PositivePattern ; NegativePattern * PositivePattern: * Prefixopt Number Suffixopt * NegativePattern: * Prefixopt Number Suffixopt * Prefix: * any Unicode characters except \uFFFE, \uFFFF, and special characters * Suffix: * any Unicode characters except \uFFFE, \uFFFF, and special characters * Number: * Integer Exponentopt * Integer . Fraction Exponentopt * Integer: * MinimumInteger * # * # Integer * # , Integer * MinimumInteger: * 0 * 0 MinimumInteger * 0 , MinimumInteger * Fraction: * MinimumFractionopt OptionalFractionopt * MinimumFraction: * 0 MinimumFractionopt * OptionalFraction: * # OptionalFractionopt * Exponent: * E MinimumExponent * MinimumExponent: * 0 MinimumExponentopt *A
DecimalFormatpattern contains a positive and negative * subpattern, for example,"#,##0.00;(#,##0.00)". Each * subpattern has a prefix, numeric part, and suffix. The negative subpattern * is optional; if absent, then the positive subpattern prefixed with the * localized minus sign (code>'-'"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 all the same as the positive * pattern. That means that"#,##0.0#;(#)"produces precisely * the same behavior as"#,##0.0#;(#,##0.0#)". * *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
DecimalFormat.parse()to be able * to distinguish positive from negative values. (If they are identical, then *DecimalFormatwill behave as if no negative subpattern was * specified.) Another example is that the decimal separator and thousands * separator should be distinct characters, or parsing will be impossible. * *The grouping separator is commonly used for thousands, but in some * countries it separates ten-thousands. The grouping size is a constant number * of digits between the grouping characters, such as 3 for 100,000,000 or 4 for * 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
"#,##,###,####"=="######,####"== *"##,####,####". * *Special Pattern Characters
* *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. * They must be quoted, unless noted otherwise, if they are to appear in the * prefix or suffix as literals. * *
The characters listed here are used in non-localized patterns. Localized * patterns use the corresponding characters taken from this formatter's *
DecimalFormatSymbolsobject instead, and these characters lose * their special status. Two exceptions are the currency sign and quote, which * are not localized. * *** **
** Symbol * Location * Localized? * Meaning * * 0*Number * Yes * Digit * * #*Number * Yes * Digit, zero shows as absent * * .*Number * Yes * Decimal separator or monetary decimal separator * * -*Number * Yes * Minus sign * * ,*Number * Yes * Grouping separator * * E*Number * Yes * Separates mantissa and exponent in scientific notation. * Need not be quoted in prefix or suffix. * * ;*Subpattern boundary * Yes * Separates positive and negative subpatterns * * %*Prefix or suffix * Yes * Multiply by 100 and show as percentage * * \u2030*Prefix or suffix * Yes * Multiply by 1000 and show as per mille * * ¤(\u00A4) *Prefix or suffix * No * Currency sign, replaced by currency symbol. If * doubled, replaced by international currency symbol. * If present in a pattern, the monetary decimal separator * is used instead of the decimal separator. * * '*Prefix or suffix * No * Used to quote special characters in a prefix or suffix, * for example, "'#'#"formats 123 to *"#123". To create a single quote * itself, use two in a row:"# o''clock". *Scientific Notation
* *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 10^3. The * mantissa is often in the range 1.0 <= x < 10.0, but it need not be. *
DecimalFormatcan be instructed to format and parse scientific * notation only via a pattern; there is currently no factory method * that creates a scientific notation format. 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". * *
-
*
- 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, not the prefix and suffix
* from the pattern. This allows patterns such as
"0.###E0 m/s". * * - The minimum and maximum number of integer digits are interpreted
* together:
*
*
-
*
- If the maximum number of integer digits is greater than their minimum number
* and greater than 1, it forces the exponent to be a multiple of the maximum
* number of integer digits, and the minimum number of integer digits to be
* interpreted as 1. The most common use of this is to generate
* engineering notation, in which the exponent is a multiple of three,
* e.g.,
"##0.#####E0". Using this pattern, the number 12345 * formats to"12.345E3", and 123456 formats to *"123.456E3". * * - Otherwise, the minimum number of integer digits is achieved by adjusting the
* exponent. Example: 0.00123 formatted with
"00.###E0"yields *"12.3E-4". *
- If the maximum number of integer digits is greater than their minimum number
* and greater than 1, it forces the exponent to be a multiple of the maximum
* number of integer digits, and the minimum number of integer digits to be
* interpreted as 1. The most common use of this is to generate
* engineering notation, in which the exponent is a multiple of three,
* e.g.,
- The number of significant digits in the mantissa is the sum of the
* minimum integer and maximum fraction digits, and is
* unaffected by the maximum integer digits. For example, 12345 formatted with
*
"##0.##E0"is"12.3E3". To show all digits, set * the significant digits count to zero. The number of significant digits * does not affect parsing. * * - Exponential patterns may not contain grouping separators. *
Rounding
* *DecimalFormat uses half-even rounding (see
* {@link java.math.BigDecimal#ROUND_HALF_EVEN ROUND_HALF_EVEN}) for
* formatting.
*
* Digits
* * For formatting,DecimalFormat uses the ten consecutive
* characters starting with the localized zero digit defined in the
* DecimalFormatSymbols object as digits. For parsing, these
* digits as well as all Unicode decimal digits, as defined by
* {@link Character#digit Character.digit}, are recognized.
*
* Special Values
* *NaN is formatted as a single character, typically
* \uFFFD. This character is determined by the
* DecimalFormatSymbols object. This is the only value for which
* the prefixes and suffixes are not used.
*
*
Infinity is formatted as a single character, typically
* \u221E, with the positive or negative prefixes and suffixes
* applied. The infinity character is determined by the
* DecimalFormatSymbols object.
*
*
Negative zero ("-0") parses to Double(-0.0),
* unless isParseIntegerOnly() is true, in which case it parses to
* Long(0).
*
*
Synchronization
* ** Decimal formats are generally not synchronized. * It is recommended to create separate format instances for each thread. * If multiple threads access a format concurrently, it must be synchronized * externally. * *
Example
* *
* // Print out a number using the localized number, integer, currency,
* // and percent format for each locale
* Locale[] locales = NumberFormat.getAvailableLocales();
* double myNumber = -1234.56;
* NumberFormat form;
* for (int j=0; j<4; ++j) {
* System.out.println("FORMAT");
* for (int i = 0; i < locales.length; ++i) {
* if (locales[i].getCountry().length() == 0) {
* continue; // Skip language-only locales
* }
* System.out.print(locales[i].getDisplayName());
* switch (j) {
* case 0:
* form = NumberFormat.getInstance(locales[i]); break;
* case 1:
* form = NumberFormat.getIntegerInstance(locales[i]); break;
* case 2:
* form = NumberFormat.getCurrencyInstance(locales[i]); break;
* default:
* form = NumberFormat.getPercentInstance(locales[i]); break;
* }
* if (form instanceof DecimalFormat) {
* System.out.print(": " + ((DecimalFormat) form).toPattern());
* }
* System.out.print(" -> " + form.format(myNumber));
* try {
* System.out.println(" -> " + form.parse(form.format(myNumber)));
* } catch (ParseException e) {}
* }
* }
* positivePrefix.
*
* This pattern is expanded by the method expandAffix() to
* positivePrefix to update the latter to reflect changes in
* symbols. If this variable is null then
* positivePrefix is taken as a literal value that does not
* change when symbols changes. This variable is always
* null for DecimalFormat objects older than
* stream version 2 restored from stream.
