Usage Notes

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: 'percent-pipe',  template: `<div>    <!--output '26%'-->    <p>A: {{ a | percent }}</p>    <!--output '0,134.950%'-->    <p>B: {{ b | percent: '4.3-5' }}</p>    <!--output '0 134,950 %'-->    <p>B: {{ b | percent: '4.3-5' : 'fr' }}</p>  </div>`,  standalone: false,})export class PercentPipeComponent {  a: number = 0.259;  b: number = 1.3495;}
