Retrieve the thousand separator for numbers using Angular in various languages

When using the English locale, numbers appear as follows: 111,111,222.00, with a comma as the thousand separator and a point as the decimal separator. In languages like German, the same number would be represented as 111.111.222,00, reversing the positions of the thousand and decimal separators. Is there a way to determine the correct thousand separator based on the chosen locale?

I came across the https://angular.io/api/common/getLocaleNumberFormat function in Angular, but I had trouble figuring out how to use it since it always seems to return the format for the English (en) locale.

Answer №1

Utilize the getLocaleNumberSymbol() function.

getLocaleNumberSymbol(locale: string, symbol: NumberSymbol): string

import { getLocaleNumberSymbol, NumberSymbol } from '@angular/common';

// Example of returning thousands separator (,) for 'en-US':
getLocaleNumberSymbol('en-US', NumberSymbol.CurrencyGroup)
// Example of returning decimal separator (.) for 'en-US':
getLocaleNumberSymbol('en-US', NumberSymbol.CurrencyDecimal)

If you are using a locale different from 'en-US', make sure to import the necessary locale data into your AppModule:

import '@angular/common/locales/global/en-GB';

@NgModule({...})
export class AppModule {
}

A list of available locales can be found at: https://github.com/angular/angular/tree/master/packages/common/locales

Answer №2

In my app.module, I typically define the global locale setting.

App.Module.ts

import { registerLocaleData } from '@angular/common';
import localeHe from '@angular/common/locales/he';

registerLocaleData(localeHe, 'he');

@NgModule({ // ....

Check out the Angular I18n documentation for more information.

Answer №3

In accordance with the guidance provided in the Angular documentation, it is necessary to specify the locale as the first argument of the getLocaleNumberFormat() function:

getLocaleNumberFormat(locale: string, type: NumberFormatStyle): string


Parameters:
locale : string A locale code for the format rules specific to the specified locale.
type : NumberFormatStyle The nature of the numeric value to be formatted (e.g., Decimal or Currency.)

If the appropriate language string is supplied, the formatting should function correctly.
