- * <code>DecimalFormat</code> is a concrete subclass of {@link NumberFormat} that 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, or Indic digits. It also supports different flavors of numbers, including integers ("123"),
- * fixed-point numbers ("123.4"), scientific notation ("1.23E4"), percentages ("12%"), and currency amounts ("$123.00",
- * "USD123.00", "123.00 US dollars"). All of these flavors can be easily localized.
- *
- * <p>
- * To obtain a {@link NumberFormat} for a specific locale (including the default locale) call one of

* <h4>Patterns</h4>
- *
- * <p>
- * A <code>DecimalFormat</code> consists of a <em>pattern</em> and a set of <em>symbols</em>. The pattern may be set
- * directly using {@link #applyPattern}, or indirectly using other API methods which manipulate aspects of the pattern,
- * such as the minimum number of integer digits. The symbols are stored in a {@link DecimalFormatSymbols} object. When
- * using the {@link NumberFormat} factory methods, the pattern and symbols are read from ICU's locale data.

+ *
* <h4>Special Pattern Characters</h4>
- *
- * <p>
- * 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. For
- * example, the '#' character is replaced by a localized digit. Often the replacement character is the same as the
- * pattern character; in the U.S. locale, the ',' grouping character is replaced by ','. However, the replacement is
- * still happening, and if the symbols are modified, the grouping character changes. Some special characters affect the
- * behavior of the formatter by their presence; for example, if the percent character is seen, then the value is
- * multiplied by 100 before being displayed.
- *
- * <p>
- * To insert a special character in a pattern as a literal, that is, without any special meaning, the character must be
- * quoted. There are some exceptions to this which are noted below.
- *
- * <p>
- * The characters listed here are used in non-localized patterns. Localized patterns use the corresponding characters
- * taken from this formatter's {@link DecimalFormatSymbols} object instead, and these characters lose their special
- * status. Two exceptions are the currency sign and quote, which are not localized.

- * <p>
- * A <code>DecimalFormat</code> pattern contains a postive and negative subpattern, for example, "#,##0.00;(#,##0.00)".
- * Each subpattern has a prefix, a numeric part, and a suffix. If there is no explicit negative subpattern, the negative
- * subpattern is the localized minus sign prefixed to the positive subpattern. That is, "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 ignored in the negative subpattern. That means
- * that "#,##0.0#;(#)" has precisely the same result as "#,##0.0#;(#,##0.0#)".
- *
- * <p>
- * 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 {@link #parse} to be able to distinguish positive from negative values.
- * Another example is that the decimal separator and thousands separator should be distinct characters, or parsing will
- * be impossible.
- *
- * <p>
- * The <em>grouping separator</em> is a character that separates clusters of integer digits to make large numbers more
- * legible. It commonly used for thousands, but in some locales it separates ten-thousands. The <em>grouping size</em>
- * is the number of digits between the grouping separators, such as 3 for "100,000,000" or 4 for "1 0000 0000". There
- * are actually two different grouping sizes: One used for the least significant integer digits, the
- * <em>primary grouping size</em>, and one used for all others, the <em>secondary grouping size</em>. In most locales
- * these are the same, but sometimes they are different. For example, if the primary grouping interval is 3, and the
- * secondary is 2, then this corresponds to the pattern "#,##,##0", and the number 123456789 is formatted as
- * "12,34,56,789". If a pattern contains multiple grouping separators, the interval between the last one and the end of
- * the integer defines the primary grouping size, and the interval between the last two defines the secondary grouping
- * size. All others are ignored, so "#,##,###,####" == "###,###,####" == "##,#,###,####".

* <h4>Parsing</h4>
- *
- * <p>
- * <code>DecimalFormat</code> parses all Unicode characters that represent decimal digits, as defined by
- * {@link UCharacter#digit}. In addition, <code>DecimalFormat</code> also recognizes as digits the ten consecutive
- * characters starting with the localized zero digit defined in the {@link DecimalFormatSymbols} object. During
- * formatting, the {@link DecimalFormatSymbols}-based digits are output.
- *
- * <p>
- * During parsing, grouping separators are ignored.
- *
- * <p>
- * For currency parsing, the formatter is able to parse every currency style formats no matter which style the formatter
- * is constructed with. For example, a formatter instance gotten from NumberFormat.getInstance(ULocale,
- * NumberFormat.CURRENCYSTYLE) can parse formats such as "USD1.00" and "3.00 US dollars".
- *
- * <p>
- * If {@link #parse(String, ParsePosition)} fails to parse a string, it returns <code>null</code> and leaves the parse
- * position unchanged. The convenience method {@link #parse(String)} indicates parse failure by throwing a
- * {@link java.text.ParseException}.
- *
- * <p>
- * Parsing an extremely large or small absolute value (such as 1.0E10000 or 1.0E-10000) requires huge memory allocation
- * for representing the parsed number. Such input may expose a risk of DoS attacks. To prevent huge memory allocation
- * triggered by such inputs, <code>DecimalFormat</code> internally limits of maximum decimal digits to be 1000. Thus, an
- * input string resulting more than 1000 digits in plain decimal representation (non-exponent) will be treated as either
- * overflow (positive/negative infinite) or underflow (+0.0/-0.0).

- * specified either through the API or through the pattern syntax. In a pattern the pad escape character, followed by a
- * single pad character, causes padding to be parsed and formatted. The pad escape character is '*' in unlocalized
- * patterns, and can be localized using {@link DecimalFormatSymbols#setPadEscape}. For example,
- * <code>"$*x#,##0.00"</code> formats 123 to <code>"$xx123.00"</code>, and 1234 to <code>"$1,234.00"</code>.

+ * <li>When padding is in effect, the width of the positive subpattern, including prefix
+ * and suffix, determines the format width. For example, in the pattern <code>"* #0
* o''clock"</code>, the format width is 10.
- *
+ *
* <li>The width is counted in 16-bit code units (Java <code>char</code>s).
- *
- * <li>Some parameters which usually do not matter have meaning when padding is used, because the pattern width is
- * significant with padding. In the pattern "* ##,##,#,##0.##", the format width is 14. The initial characters "##,##,"
- * do not affect the grouping size or maximum integer digits, but they do affect the format width.
- *
- * <li>Padding may be inserted at one of four locations: before the prefix, after the prefix, before the suffix, or
- * after the suffix. If padding is specified in any other location, {@link #applyPattern} throws an
- * {@link IllegalArgumentException}. If there is no prefix, before the prefix and after the prefix are equivalent,
- * likewise for the suffix.
- *
- * <li>When specified in a pattern, the 16-bit <code>char</code> immediately following the pad escape is the pad
- * character. This may be any character, including a special pattern character. That is, the pad escape <em>escapes</em>
- * the following character. If there is no character after the pad escape, then the pattern is illegal.

- * 1250. 1.234 rounded to the nearest 0.65 is 1.3. The rounding increment may be specified through the API or in a
