<a name="details" id="details"></a><h2 class="groupheader">Detailed Description</h2>
<div class="textblock"><p>Defines rules for mapping non-negative numeric values onto a small set of keywords. </p>
<p>Rules are constructed from a text description, consisting of a series of keywords and conditions. The <a class="el" href="classicu_1_1PluralRules.html#abac3659822d4e6ce4ebc1b32277e42b5">select</a> method examines each condition in order and returns the keyword for the first condition that matches the number. If none match, default rule(other) is returned.</p>
<p>For more information, details, and tips for writing rules, see the LDML spec, C.11 Language Plural Rules: <a href="http://www.unicode.org/draft/reports/tr35/tr35.html#Language_Plural_Rules">http://www.unicode.org/draft/reports/tr35/tr35.html#Language_Plural_Rules</a></p>
<p>Examples:</p><pre>
"one: n is 1; few: n in 2..4"</pre><p> This defines two rules, for 'one' and 'few'. The condition for 'one' is "n is 1" which means that the number must be equal to 1 for this condition to pass. The condition for 'few' is "n in 2..4" which means that the number must be between 2 and 4 inclusive for this condition to pass. All other numbers are assigned the keyword "other" by the default rule. </p>
<pre>
"zero: n is 0; one: n is 1; zero: n mod 100 in 1..19"</pre><p> This illustrates that the same keyword can be defined multiple times. Each rule is examined in order, and the first keyword whose condition passes is the one returned. Also notes that a modulus is applied to n in the last rule. Thus its condition holds for 119, 219, 319... </p>
<pre>
"one: n is 1; few: n mod 10 in 2..4 and n mod 100 not in 12..14"</pre><p> This illustrates conjunction and negation. The condition for 'few' has two parts, both of which must be met: "n mod 10 in 2..4" and "n mod 100 not in 12..14". The first part applies a modulus to n before the test as in the previous example. The second part applies a different modulus and also uses negation, thus it matches all numbers <em>not</em> in 12, 13, 14, 112, 113, 114, 212, 213, 214... </p>
<p>Syntax:</p><pre>

</pre><p>The i, f, and v values are defined as follows: </p>
<ul>
<li>
i to be the integer digits. </li>
<li>
f to be the visible fractional digits, as an integer. </li>
<li>
v to be the number of visible fraction digits. </li>
<li>
j is defined to only match integers. That is j is 3 fails if v != 0 (eg for 3.1 or 3.0). </li>
</ul>
<p>Examples are in the following table: </p>
<table border="1" style="border-collapse:collapse">
</table>
<p>n </p>
<p>i </p>
<p>f </p>
<p>v </p>

<p>The difference between 'in' and 'within' is that 'in' only includes integers in the specified range, while 'within' includes all values. Using 'within' with a range_list consisting entirely of values is the same as using 'in' (it's not an error). </p>
<p>An "identifier" is a sequence of characters that do not have the Unicode Pattern_Syntax or Pattern_White_Space properties. </p>
<p>The difference between 'in' and 'within' is that 'in' only includes integers in the specified range, while 'within' includes all values. Using 'within' with a range_list consisting entirely of values is the same as using 'in' (it's not an error). </p>
<p>Keywords could be defined by users or from ICU locale data. There are 6 predefined values in ICU - 'zero', 'one', 'two', 'few', 'many' and 'other'. Callers need to check the value of keyword returned by <a class="el" href="classicu_1_1PluralRules.html#abac3659822d4e6ce4ebc1b32277e42b5">select</a> method. </p>
<p>Examples:</p><pre>
<a class="el" href="classicu_1_1UnicodeString.html" title="UnicodeString is a string class that stores Unicode characters directly and provides similar function...">UnicodeString</a> keyword = pl->select(number);
if (keyword== <a class="el" href="classicu_1_1UnicodeString.html" title="UnicodeString is a string class that stores Unicode characters directly and provides similar function...">UnicodeString</a>("one") {
...
}
else if ( ... )
</pre><p> <b>Note:</b><br />
</p>
<p>ICU defines plural rules for many locales based on CLDR <em>Language Plural Rules</em>. For these predefined rules, see CLDR page at <a href="http://unicode.org/repos/cldr-tmp/trunk/diff/supplemental/language_plural_rules.html">http://unicode.org/repos/cldr-tmp/trunk/diff/supplemental/language_plural_rules.html</a> </p>
