NAME
   CLDR::Number - Localized number formatters using the Unicode CLDR

VERSION
   This document describes CLDR::Number v0.19, built with Unicode CLDR v29.

SYNOPSIS
       use CLDR::Number;

       # new object with 'es' (Spanish) locale
       $cldr = CLDR::Number->new(locale => 'es');

       # decimals
       $decf = $cldr->decimal_formatter;

       # when locale is 'es' (Spanish)
       say $decf->format(1234.5);  # '1234,5'

       # when locale is 'es-MX' (Mexican Spanish)
       say $decf->format(1234.5);  # '1,234.5'

       # when locale is 'ar' (Arabic)
       say $decf->format(1234.5);  # '١٬٢٣٤٫٥'

       # percents
       $perf = $cldr->percent_formatter;

       # when locale is 'tr' (Turkish)
       say $perf->format(0.05);  # '%5'

       # currencies
       $curf = $cldr->currency_formatter(currency_code => 'USD');

       # when locale is 'en' (English) and currency is USD (US dollars)
       say $curf->format(9.99);  # '$9.99'

       # when locale is 'en-CA' (Canadian English) and currency is USD
       say $curf->format(9.99);  # 'US$9.99'

       # when locale is 'fr-CA' (Canadian French) and currency is USD
       say $curf->format(9.99);  # '9,99 $ US'

DEPRECATION
   Using the "locale" method as a setter is deprecated. In the future the
   object’s locale will become immutable. Please see issue #38
   <https://github.com/patch/cldr-number-pm5/issues/38> for details and to
   submit comments or concerns.

DESCRIPTION
   Software localization includes much more than just translations.
   Numbers, prices, and even percents should all be localized based on the
   user’s language, script, and region. Fortunately, the Unicode Common
   Locale Data Repository (CLDR) provides locale data and specifications
   for formatting numeric data to use with many of the world’s locales.

   This class provides common attributes shared among the supported
   formatter classes as well as methods to instantiate decimal, percent,
   and currency formatter objects. The value for any attribute (such as
   locale or decimal_sign) will be passed to the formatter objects on
   instantiation but can be overwritten by manually passing another value
   for the attribute or calling a setter method on the formatter object.

 Methods
   decimal_formatter
       Returns a decimal formatter, which is a
       CLDR::Number::Format::Decimal object instantiated with all of the
       attributes from your CLDR::Number object as well as any attributes
       passed to this method.

   percent_formatter
       Returns a percent formatter, which is a
       CLDR::Number::Format::Percent object instantiated with all of the
       attributes from your CLDR::Number object as well as any attributes
       passed to this method.

   currency_formatter
       Returns a currency formatter, which is a
       CLDR::Number::Format::Currency object instantiated with all of the
       attributes from your CLDR::Number object as well as any attributes
       passed to this method.

 Common Attributes
   These are common attributes among this class and all formatter classes.
   All attributes other than locale, default_locale, and cldr_version have
   defaults that change depending on the current locale. All string
   attributes are expected to be character strings, not byte strings.

   locale
       Default: value of default_locale attribute if it exists, otherwise
       "root"

       Valid: Unicode locale identifiers

       Examples: "es" (Spanish), "es-ES" (European Spanish), "es-419"
       (Latin American Spanish), "zh-Hant" (Traditional Chinese), "zh-Hans"
       (Simplified Chinese), "chr" (Cherokee)

       The locale is case-insensitive and can use either "-" (hyphen-minus)
       or "_" (low line) as a separator.

   default_locale
       Default: none

       Valid: Unicode locale identifiers

       Use this if you want a locale other than the generic "root" if the
       locale attribute is not set or not valid.

   numbering_system
       Valid: currently only decimal numbering systems are supported

       Examples: "latn" (Western Digits), "arab" (Arabic-Indic Digits),
       "hanidec" (Chinese Decimal Numerals), "fullwide" (Full Width Digits)

       In the future, algorithmic numbering systems like "hant"
       (Traditional Chinese Numerals), "hebr" (Hebrew Numerals), and
       "roman" (Roman Numerals) will be supported.

       The numbering system may alternately be provided as a Unicode locale
       extension subtag. For example, locale "ja-u-nu-fullwide" for the
       Japanese language ("ja") with the numbering system ("nu") set to
       Full Width Digits ("fullwide").

   decimal_sign
       Examples: "." (full stop) for root, en; "," (comma) for de, fr

   group_sign
       Examples: "," (comma) for root, en; "." (full stop) for de; " "
       (no-break space) for fr

   plus_sign
       Examples: "+" (plus sign) for root, en, and most locales

   minus_sign
       Examples: "-" (hyphen-minus) for root, en, and most locales

   infinity
       Examples: "∞" (infinity) for root, en, and almost all locales

   nan Examples: "NaN" for root, en, and most locales; many other
       variations for individual locales like "не число" for ru and "非數值"
       for zh-Hant

   cldr_version
       Value: 29

       This is a read-only attribute that will always reflect the currently
       supported Unicode CLDR version.

NOTES
   The Unicode private-use characters U+F8F0 through U+F8F4 are used
   internally and are therefore not supported in custom patterns and signs.
