Angular2 Currency Pipe change decimal separator

Your problem has probably been solved some time ago, but just for reference for other Dutch developers (like myself):

Create a custom Pipe:

import {Pipe} from '@angular/core';
 
@Pipe({
    name: 'currencyFormat'
})
export class CurrencyFormat {
    transform(value: number,
        currencySign: string = '€ ',
        decimalLength: number = 2, 
        chunkDelimiter: string = '.', 
        decimalDelimiter:string = ',',
        chunkLength: number = 3): string {

        value /= 100;

        let result = '\\d(?=(\\d{' + chunkLength + '})+' + (decimalLength > 0 ? '\\D' : '$') + ')';
        let num = value.toFixed(Math.max(0, ~~decimalLength));

        return currencySign+(decimalDelimiter ? num.replace('.', decimalDelimiter) : num).replace(new RegExp(result, 'g'), '$&' + chunkDelimiter);
    }
}

Now you can use:

{{someIntegerWithCentsToBeDivided | currencyFormat}}

The Pipe has already all the Dutch defaults included, but you can easily change them or use them as arguments in the template. For example:

{{1234567 | currencyFormat:'$':2:' ':'.':3}}

will give $12 345.67 as output.

you need import that

import { registerLocaleData } from '@angular/common';
import localeIt from '@angular/common/locales/it'
registerLocaleData(localeIt, 'it');

and add that pipe in view

{{ 1000 | currency: 'EUR':'symbol':'.2-2':'it' }}
