Unicode number formatting API
This module helps you to format and parse numbers for any locale. Your code can be completely independent of the locale conventions for decimal points, thousands-separators, or even the particular decimal digits used, or whether the number format is even decimal. There are different number format styles like decimal, currency, percent and spelled-out.
Use formatter
to create a formatter and format
to format numbers.
:: NumberFormatStyle | The type of number format to open. If NUM_PATTERN_DECIMAL or NUM_PATTERN_RULEBASED is passed then the number format is opened using the given pattern, which must conform to the syntax described in DecimalFormat or RuleBasedNumberFormat, respectively. |
-> LocaleName | A locale identifier to use to determine formatting and parsing conventions, or NULL to use the default locale, e.g. "de_DE". |
-> NumberFormat |
Create and return a new NumberFormat for formatting and parsing numbers.
A NumberFormat may be used to format numbers by calling unum_format, and to parse numbers by calling unum_parse. The caller must call unum_close when done to release resources used by this object.
class FormattableNumber n Source #
Format an integer using a NumberFormat.
The integer will be formatted according to the UNumberFormat's locale.

data NumberFormatStyle Source #
The possible number format styles.
NUM_PATTERN_DECIMAL Text | Decimal format defined by a pattern string. See the section "Patterns" at https://unicode-org.github.io/icu-docs/apidoc/released/icu4c/classDecimalFormat.html#Patterns for further details regarding pattern strings. |
NUM_DECIMAL | Decimal format ("normal" style). |
NUM_CURRENCY | Currency format (generic). Defaults to UNUM_CURRENCY_STANDARD style (using currency symbol, e.g., "$1.00", with non-accounting style for negative values e.g. using minus sign). The specific style may be specified using the -cf- locale key. |
NUM_PERCENT | Percent format. |
NUM_SCIENTIFIC | Scientific format. |
NUM_SPELLOUT | Spellout rule-based format. The default ruleset can be specified/changed using unum_setTextAttribute with UNUM_DEFAULT_RULESET; the available public rulesets can be listed using unum_getTextAttribute with UNUM_PUBLIC_RULESETS. |
NUM_ORDINAL | Ordinal rule-based format. The default ruleset can be specified/changed using unum_setTextAttribute with UNUM_DEFAULT_RULESET; the available public rulesets can be listed using unum_getTextAttribute with UNUM_PUBLIC_RULESETS. |
NUM_DURATION | Duration rule-based format. |
NUM_NUMBERING_SYSTEM | Numbering system rule-based format. |
NUM_PATTERN_RULEBASED Text | Rule-based format defined by a pattern string. See the section "Patterns" at https://unicode-org.github.io/icu-docs/apidoc/released/icu4c/classDecimalFormat.html#Patterns for further details regarding pattern strings. |
NUM_CURRENCY_ISO | Currency format with an ISO currency code, e.g., "USD1.00". |
NUM_CURRENCY_PLURAL | Currency format with a pluralized currency name, e.g., "1.00 US dollar" and "3.00 US dollars". |
NUM_CURRENCY_ACCOUNTING | Currency format for accounting, e.g., "($3.00)" for negative currency amount instead of "-$3.00" (UNUM_CURRENCY). Overrides any style specified using -cf- key in locale. |
NUM_CASH_CURRENCY | Currency format with a currency symbol given CASH usage, e.g., "NT$3" instead of "NT$3.23". |
NUM_DECIMAL_COMPACT_SHORT | Decimal format expressed using compact notation (short form, corresponds to UNumberCompactStyle=UNUM_SHORT) e.g. "23K", "45B" |
NUM_DECIMAL_COMPACT_LONG | Decimal format expressed using compact notation (long form, corresponds to UNumberCompactStyle=UNUM_LONG) e.g. "23 thousand", "45 billion" |
NUM_CURRENCY_STANDARD | Currency format with a currency symbol, e.g., "$1.00", using non-accounting style for negative values (e.g. minus sign). Overrides any style specified using -cf- key in locale. |
NUM_FORMAT_STYLE_COUNT | One more than the highest normal UNumberFormatStyle value. Deprecated: ICU 58 The numeric value may change over time, see ICU ticket #12420. |
NUM_DEFAULT | Default format. |
NUM_IGNORE | Alias for NUM_PATTERN_DECIMAL. |
