.currencyFormatter( currency [, options] ) ➜ function( value )

Return a function that formats a currency according to the given options or locale's defaults.

The returned function is invoked with one argument: the Number value to be formatted.

Parameters

currency

3-letter currency code as defined by ISO 4217, eg. "USD".

options.style

Optional. String "symbol" (default), "accounting", "code" or "name". See .numberFormatter( [options] ) for more options.

value

Number to be formatted, eg. 9.99.

Example

Static Formatter

Prior to using any currency methods, you must load cldr/main/{locale}/currencies.json, cldr/supplemental/currencyData.json, and the CLDR content required by the number module. If using plural messages, you also must load the CLDR content required by the plural module. Read CLDR content if you need more information.

Using the default options

You can use the static method Globalize.currencyFormatter(), which uses the default locale.

var formatter;

Globalize.locale( "en" );
formatter = Globalize.currencyFormatter( "USD" );

formatter( 9.99 );
// > "$9.99"

Instance Formatter

You can use the instance method .currencyFormatter(), which uses the instance locale.

var deFormatter = Globalize( "de" ).currencyFormatter( "EUR" ),
  zhFormatter = Globalize( "zh" ).currencyFormatter( "EUR" );

deFormatter( 9.99 );
// > "9,99 €"

zhFormatter( 9.99 );
// > "€ 9.99"

For comparison, follow the formatting output of different symbols in different locales.

3-letter currency code	en (English)	de (German)	zh (Chinese)
.currencyFormatter( "USD" )( 1 )	$1.00	1,00 $	US$ 1.00
.currencyFormatter( "EUR" )( 1 )	€1.00	1,00 €	€ 1.00
.currencyFormatter( "CNY" )( 1 )	CN¥1.00	1,00 CN¥	￥ 1.00
.currencyFormatter( "JPY" )( 1 )	¥1	1 ¥	JP¥ 1
.currencyFormatter( "GBP" )( 1 )	£1.00	1,00 £	£ 1.00
.currencyFormatter( "BRL" )( 1 )	R$1.00	1,00 R$	R$ 1.00

Using alternative options.symbolForm

Using the narrow symbol form, the same symbols may be used for multiple currencies. Thus the symbol may be ambiguous, and should only be used where the context is clear.

Globalize( "en" ).currencyFormatter( "HKD" )( 1 );
// > "HK$1.00"

Globalize( "en" ).currencyFormatter( "HKD", { symbolForm: "narrow" } )( 1 );
// > "$1.00"

Configuring style

For the accounting variation of the symbol format, use style: "accounting".

var formatter = Globalize( "en" ).currencyFormatter( "USD", {
  style: "accounting"
});

formatter( -1 );
// > "($1.00)"

For plural messages, use style: "name".

var formatter = Globalize( "en" ).currencyFormatter( "USD", {
  style: "name"
});

formatter( 0 );
// > "0.00 US dollars"

formatter( 1 );
// > "1.00 US dollar"

For comparison, follow the formatting output of different symbols in different locales using the plural messages Globalize( locale ).currencyFormatter( currency, { style: "name" } )( 1 ).

3-letter currency code	en (English)	de (German)	zh (Chinese)
USD	1.00 US dollar	1,00 US-Dollar	1.00美元
EUR	1.00 euro	1,00 Euro	1.00欧元
CNY	1.00 Chinese yuan	1,00 Chinesischer Yuan	1.00人民币
JPY	1 Japanese yen	1 Japanischer Yen	1日元
GBP	1.00 British pound sterling	1,00 Britisches Pfund Sterling	1.00英镑
BRL	1.00 Brazilian real	1,00 Brasilianischer Real	1.00巴西雷亚尔

For the international currency code, use style: "code".

var formatter = Globalize( "en" ).currencyFormatter( "USD", {
  style: "code"
});

formatter( 9.99 );
// > "9.99 USD"

Configuring inherited number options

Override the number of digits, grouping separators, rounding function or any other .numberFormatter() options.

var formatter;

Globalize.locale( "en" );
formatter = Globalize.currencyFormatter( "USD", {
  minimumFractionDigits: 0,
  style: "name"
});

formatter( 1 );
// > "1 US dollar"

formatter = Globalize.currencyFormatter( "USD", {
  round: "ceil"
});

formatter( 1.491 );
// > "$1.50"

Formatting Compact Currencies

var shortFormatter = Globalize( "en" ).currencyFormatter( "USD", {
  compact: "short"
});

var longFormatter = Globalize( "en" ).currencyFormatter( "USD", {
  compact: "long"
});

shortFormatter( 12830000000 );
// > "$13B"

longFormatter( 12830000000 );
// > "$13 billion"

The minimumSignificantDigits and maximumSignificantDigits options are specially useful to control the number of digits to display.

Globalize( "en" ).formatCurrency( 12830000000, "USD", {
  compact: "short",
  minimumSignificantDigits: 3,
  maximumSignificantDigits: 3
});
// > "$12.8B"

Performance Suggestion

For improved performance on iterations, first create the formatter. Then, reuse it on each loop.

var formatter = Globalize( "en" ).currencyFormatter( "USD" );

renderInvoice({
  prices: prices.map(function( price ) {
    return formatter( price );
  })
});
