Angular 2 formatting currency BRL format

问题:

I'm trying to use pipe to format the price of an item in PT-BR currency format.

Here what i'm trying to do:

<div class="desc">{{statement.price | currency:'BRL':true:'1.2-2'}} </div>  

The result that i expect is 33.111,00 and now is returning 33,111.00 .

You can set the locale-id. Import the module as follows:

import {LOCALE_ID} from '@angular/core';

And in your module define a provider like this:

providers: [
    {
      provide: LOCALE_ID,
      useValue: "en-US"
    }
]

Just exchange for your locale ID (for IDs, refer to the Angular documentation).

I solve....

import { Pipe, PipeTransform } from '@angular/core';
import { CurrencyPipe } from '@angular/common';

@Pipe({
  name: 'currencyformat'
})
export class CurrencyFormatPipe implements PipeTransform {

  transform(value: number, currencyCode: string = 'BRL', symbolDisplay: boolean = true, digits?: string): string {
    if (!value) {
      return '';
    }

    let currencyPipe: CurrencyPipe = new CurrencyPipe('pt-BR');
    let newValue: string = currencyPipe.transform(value, currencyCode, symbolDisplay, digits);

    return newValue;
  }

}

For me it worked after importing the locale, as mentioned by Marcelo Vieira das Neves.

1. Import locale in your module:

import { LOCALE_ID } from '@angular/core';

providers: [{provide: LOCALE_ID, useValue: 'pt-BR'}]

2. Use the currency pipe

{{item.limite | currency:'BRL':true}}

I was trying to format my number to Brazilian currency using this pipe

{{p.preco | currency : 'R$' }}

and I had to put the following lines in app.module.ts in order to format the currency correctly (i.e. R$ 12,00)

import {LOCALE_ID} from '@angular/core';
import localePt from '@angular/common/locales/pt';
import {registerLocaleData} from '@angular/common';

registerLocaleData(localePt, 'pt');

@NgModule({
    declarations: [/*...*/],
    imports: [/*...*/],
    providers: [
        {
            provide: LOCALE_ID,
            useValue: 'pt'
        }
    ]
})

It didn't work out until I add the registerLocaleData call

I'm using angular 8, hope it helps!

Do that:

getFormattedPrice(price: number) {
    return new Intl.NumberFormat('pt-BR', { style: 'currency', currency: 'BRL' }).format(price);
}

Which browser are you using, as stated in the code:

WARNING: this pipe uses the Internationalization API. Therefore it is only reliable in Chrome and Opera browsers. For other browsers please use an polyfill, for example: [https://github.com/andyearnshaw/Intl.js/].

Probably you are best to use another library like the one they mentioned.

i solved this way:

import { Pipe, PipeTransform } from '@angular/core';
import { CurrencyPipe } from '@angular/common';

@Pipe({
  name: 'currencyFormat'
})
export class CurrencyFormatPipe implements PipeTransform {
    transform(value: number, locale: string, currency_symbol: boolean, number_format: string = '1.2-2'): string {
        if (value) {

            let currencyPipe = new CurrencyPipe();
            let new_value: string;

            new_value = currencyPipe.transform(value, locale, currency_symbol, number_format);
            if (locale = 'BRL') {
                new_value = new_value.replace('.', '|').replace(',', '.').replace('|', ',');
            } 

            return new_value                                    
        }
    }
}

I solved with an workaround that adapts based on country:

import { Pipe, PipeTransform, LOCALE_ID, Inject } from '@angular/core';
import { getLocaleCurrencySymbol, getLocaleCurrencyName } from 
'@angular/common';

@pipe({
name: 'currencyGlobal'
})
export class CurrencyGlobalPipe implements PipeTransform {
  constructor(@Inject(LOCALE_ID) public locale: string){
  }

  transform(value: number): any {
    return getLocaleCurrencySymbol(this.locale) + new 
     Intl.NumberFormat(this.locale, { style: 'decimal', minimumFractionDigits: 2 
   }).format(value);
}

}

Couldn't use the Intl style:'currency' because the getLocaleCurrencyName doens't return the same as the documentation says it does (https://angular.io/api/common/getLocaleCurrencyName), should be 'USD' but return 'US Dollar', so I did an workaround with currencySimbol + decimal.

Maybe it can help someone else
