說明

Deprecation notice:

The default currency code is currently always USD but this is deprecated from v9.

In v11 the default currency code will be taken from the current locale identified by the LOCALE_ID token. See the i18n guide for more information.

If you need the previous behavior then set it by creating a DEFAULT_CURRENCY_CODE provider in your application NgModule:

      
      {provide: DEFAULT_CURRENCY_CODE, useValue: 'USD'}

使用說明

The following code shows how the pipe transforms numbers into text strings, according to various format specifications, where the caller's default locale is en-US.

      
      @Component({
  selector: 'currency-pipe',
  template: `<div>
    <!--output '$0.26'-->
    <p>A: {{a | currency}}</p>

    <!--output 'CA$0.26'-->
    <p>A: {{a | currency:'CAD'}}</p>

    <!--output 'CAD0.26'-->
    <p>A: {{a | currency:'CAD':'code'}}</p>

    <!--output 'CA$0,001.35'-->
    <p>B: {{b | currency:'CAD':'symbol':'4.2-2'}}</p>

    <!--output '$0,001.35'-->
    <p>B: {{b | currency:'CAD':'symbol-narrow':'4.2-2'}}</p>

    <!--output '0 001,35 CA$'-->
    <p>B: {{b | currency:'CAD':'symbol':'4.2-2':'fr'}}</p>

    <!--output 'CLP1' because CLP has no cents-->
    <p>B: {{b | currency:'CLP'}}</p>
  </div>`
})
export class CurrencyPipeComponent {
  a: number = 0.259;
  b: number = 1.3495;
}
