Get currency information

import * as argonFormatter from 'argon-formatter';

argonFormatter.findCurrency('USD');
// returns:
// {
//   code: 'USD',
//   symbol: '

,
//   thousandsSeparator: ',',
//   decimalSeparator: '.',
//   symbolOnLeft: true,
//   spaceBetweenAmountAndSymbol: false,
//   decimalDigits: 2
// }

Unformat

argonFormatter.unformat('$10.5', { code: 'USD' })
// => 10.5

argonFormatter.unformat('$1,000,000', { code: 'USD' })
// => 1000000

argonFormatter.unformat('10,5 €', { code: 'EUR' })
// => 10.5

argonFormatter.unformat('1 000 000,00 €', { code: 'EUR' })
// => 1000000

argonFormatter.unformat('1.000,99', { locale: 'de-DE' })
// => 1000.99

argonFormatter.unformat('10\'000 CHF', { code: 'CHF' })
// => 10000

argonFormatter.unformat('10.00 CHF', { code: 'CHF' })

Advanced Usage

Argon Formatter uses accounting under the hood, and you can use its options to override default behavior.

import * as argonFormatter from 'argon-formatter';
argonFormatter.format(1000000, {
  symbol: '@',
  decimal: '*',
  thousand: '^',
  precision: 1,
  format: '%v %s' // %s is the symbol and %v is the value
});

// => '1^000^000*0 @'

// Different formatting for positive and negative values
argonFormatter.format(-10, {
  format: {
    pos: '%s%v' // %s is the symbol and %v is the value
    neg: '(%s%v)',
    zero: '%s%v'
  }
});

// => ($10)
