Properties

Property	Type	Description

symbolFormat	String (enum)	Position of the symbol. Possible values: none, prefix and postfix. Default: prefix.

noNegative	Boolean	When true doesn't shown negative sign

Global Configuration

With the library we have shipped few currencies configuration, see currency-config.js. That should be sufficient for most of the use-case.

Change global configuration

Sample configuration for a (single) currency is as follows:

{
  symbol: "₹",
  thousandSeparator: ',',
  decimalSeparator: '.',
  thousandSpacing: '2s',
  decimalPoints: 2,
  valueDivider: 1
}

We can change a configuration for any existing currency, or add a new currency to the config as follows.

import { DwCurrency } '@dreamworld/dw-currency';
DwCurrency.setConfig({
    USD: {
        symbol: '$',
        thousandSpacing: '3'
    },
    MYCURRENCY: {
        symbol: "MC",
        valueDivider: 100
    }
});

Currency Config

Configuration name	Type	Description
symbol	String	Currency Symbol
thousandSeparator	String	Character to be used as thousand separator. Default value: , (comma)
decimalSeparator	String	Character to be used as decimal separator. Default value: . (dot)
thousandSpacing	String (enum)	How many numbers are grouped for thousand separator. Possible values are 2, 2s, 3, 4. Default value: 3. Whne 2 will format like 1,23,45,67,89. When 3 will format like 1,234,567,981. When 2s will format like 1,23,45,67,981. When 4 will format like 1,2345,6789.
symbolStyle	Object
decimalPoints	Number	Precision. Number of digits after decimal points. Default value: 2.
valueDivider	Number	1

Change Defaults

Default config for all the currencies are as follows. It's defined in currency-config.js.

{
  thousandSeparator: ',',
  decimalSeparator: '.',
  thousandSpacing: '3',
  decimalPoints: 2,
  valueDivider: 1
}

And this defaults can be overriden for your application (at global level), using following:

import { DwCurrency } '@dreamworld/dw-currency';
DwCurrency.setDefaults({
  thousandSeparator: ',',
  decimalSeparator: '.',
  thousandSpacing: '3',
  decimalPoints: 2,
  valueDivider: 100
});

setDefaultCurrency

DwCurrency.setDefaultsCurrrency("INR");
