Internationalization

24 Jan 202324 minutes to read

The Internationalization library provided by Syncfusion enables formatting and parsing of date and number objects using official Unicode CLDR JSON data. By default, the en-US locale is set as the default culture, and USD is set as the default currency code for all Syncfusion Angular UI Components.

Loading CLDR-JSON Data

It is necessary to load the following CLDR data using the loadCldr function for cultures other than en-US.

File Name Path
ca-gregorian cldr/main/en/ca-gregorian.json
timeZoneNames cldr/main/en/timeZoneNames.json
numbers cldr/main/en/numbers.json
numberingSystems cldr/supplemental/numberingSystems.json
currencies cldr/main/en/currencies.json

Note: For en, dependency files are already loaded in the library.

Installing CLDR data

CLDR data is available as an npm package. So, you can instal it by adding the below command to our package.

npm install cldr-data

Binding to i18n library

The i18n library to use the CLDR data to format, parse number and date/time values in a way that is appropriate for the en culture. The loadCldr function takes two arguments, enNumberData and enTimeZoneData, which are the CLDR data for numbers and time zones, respectively, for the en culture.

import { loadCldr } from '@syncfusion/ej2-base';
import enNumberData from 'cldr-data/main/en/numbers.json';
import enTimeZoneData from 'cldr-data/main/en/timeZoneNames.json';

loadcldr(enNumberData, entimeZoneData);

Changing global Culture and Currency code

To set the default culture and the currency code for all Syncfusion Angular UI Components, you can use the methods setCulture for setting the default locale and setCurrencyCode for setting the currency code.

import {setCulture, setCurrencyCode} from '@syncfusion/ej2-base';

setCulture('ar');
setCurrencyCode('QAR');

Note: If global culture is not set, then en-US is set as the default locale, and USD is set as the default currency code.

Manipulating Numbers

Supported format string

Based on the  NumberFormatOptions number formatting and parsing operations are processed. You need to specify some or all of the following properties mentioned in the table below

No Properties Description
1 format Denotes the format to be set .Possible values are
1. N - denotes numeric type
2. C - denotes currency type
3. P - denotes percentage type.
Ex:
formatNumber( 1234344 ,{format:'N4'}).

>Note: If no format is specified it takes numeric as default format type.
2 minimumFractionDigits Indicates the minimum number of fraction digits . Possible values are 0 to 20.
3 maximumFractionDigits Indicates the maximum number of fraction digits. Possible values are 0 to 20.
4 minimumSignificantDigits Indicates he minimum number of significant digits. Possible values are 1 to 21.
>Note: If minimumSignificantDigits is given it is mandatory to give maximumSignificantDigits
5 maximumSignificantDigits Indicates he maximum number of significant digits. . Possible values are 1 to 21.
>Note: If maximumSignificantDigits is given it is mandatory to give minimumSignificantDigits
6 useGrouping Indicates whether to enable the group separator or not . By default grouping value will be true.
7 minimumIntegerDigits Indicates the minimum number of the integer digits to be placed in the value. Possible values are 1 to 21.
8 currency Indicates the currency code which needs to considered for the currency formatting.

Note: The minimumIntegerDigits, minimumFractionDigits and maximumFractionDigits are categorized
as group one, minimumSignificantDigits and maximumSignificantDigits are categorized as group two.
If group two properties are defined, then group one properties will be ignored.

Custom number formatting and parsing

Custom number formatting and parsing can also be achieved by directly specifying the pattern in the format property of NumberFormatOptions. One or more of the custom format specifiers listed in the table below can be used to create custom number format.

Specifier Description Input Format Output
0 Replaces the zero with the corresponding digit if one is present. Otherwise, zero appears in the result string. instance.formatNumber(123,{format: ‘0000’ }) ‘0123’
# Replaces the “#” symbol with the corresponding digit if one is present; otherwise, no digit appears in the result string. instance.formatNumber(1234,{format: ‘####’ }) ‘1234’
. Denotes the number of digits allowed after the decimal points if it’s not specified then no need to specify decimal point values. instance.formatNumber(546321,{format: ‘###0.##0#’ }) ‘546321.000’
% Percent specifier denotes the percentage type format. instance.formatNumber(1,{format: ‘0000 %’ }) ‘0100 %’
$ Denotes the currency type format based on the global currency code specified. instance.formatNumber(13,{format: ‘$ ###.00’ }); ‘$ 13.00’
; Denotes separate formats for positive, negative and zero values. instance.formatNumber(-120,{format: ‘###.##;(###.00);-0’}); ‘(120.00)’
‘String’ (single Quotes) Denotes the characters enclosed within single Quote(‘) to be replaced in the resultant string. instance.formatNumber(-123.44,{format: “####.## ‘@’”}) ‘123.44 @’

Note: If a custom format pattern is specified, other NumberFormatOptions properties will not be considered.

Custom formats

To use the custom date and time formats, we need to specify the date/time pattern directly in the format property.
A custom format string must contain one or more of the following standard date/time symbols.

Symbols Description
G Denotes the era in the date
y Denotes the year.
M / L Denotes month.
E / c Denotes the day of week.
d Denotes the day of month.
h / H Denotes the hour. h for 12 hour and H for 24 hours format.
m Denotes minutes.
s Denotes seconds.
a Denotes the am/pm designator it will only be displayed if hour is specified in the h format.
z Denotes the time zone.
’ (single quotes) To display words in the formatted date you can specify the words with in the single quotes

Custom format example

import { Component } from '@angular/core';
import { Internationalization } from  '@syncfusion/ej2-base';

@Component({
    selector: 'app-root',
    templateUrl:`default.html`
})

export class AppComponent {
    ngAfterViewInit() {
        let intl: Internationalization = new Internationalization();
        let formattedString: string =  intl.formatDate(new Date('1/12/2014 10:20:33'), { format:'\'year:\'y' \'month:\' MM' });
        //Output: "year:2014 month:01"
        }
