In this article, we are going to see what is formatCurrency in Angular 10 and how to use it. The formatCurrency is used to format a number as currency using locale rules.
Syntax:
formatCurrency(value, locale, currency, currencyCode, digitsInfo)
Parameters:
- value: The number to format.
- locale: A locale code for the locale format.
- currency: A string containing the currency symbol or its name.
- currencyCode: the currency code.
- digitsInfo: Decimal representation options.
Return Value:
- string: the formatted currency code.
NgModule: Module used by formatCurrency is:
- CommonModule
Approach:
- Create the Angular app to be used.
- In app.module.ts import LOCALE_ID because we need locale to be imported for using get formatCurrency.
import { LOCALE_ID, NgModule } from '@angular/core';
- In app.component.ts import formatCurrency and LOCALE_ID
- inject LOCALE_ID as a public variable.
- In app.component.html show the local variable using string interpolation
- Serve the angular app using ng serve to see the output.
Example 1:
app.component.ts
import { formatCurrency
}
from '@angular/common' ;
import {Component, Inject,
LOCALE_ID }
from '@angular/core' ;
@Component({ selector: 'app-root' ,
templateUrl: './app.component.html'
}) export class AppComponent { curr = formatCurrency(10, this .locale,
'USD' );
constructor( @Inject(LOCALE_ID) public locale: string,){}
} |
app.component.html
< h1 >
GeeksforGeeks
</ h1 >
< p >Locale Currency is : {{curr}}</ p >
|
Output:
