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;
}
