[component-header:sl-format-number]

Formats a number using the specified locale and options.

Localization is handled by the browser's Intl.NumberFormat API. No language packs are required.

<div class="format-number-overview">
  <sl-format-number value="1000"></sl-format-number>
  <br /><br />
  <sl-input type="number" value="1000" label="Number to Format" style="max-width: 180px;"></sl-input>
</div>

<script>
  const container = document.querySelector('.format-number-overview');
  const formatter = container.querySelector('sl-format-number');
  const input = container.querySelector('sl-input');

  input.addEventListener('sl-input', () => (formatter.value = input.value || 0));
</script>

import { useState } from 'react';
import { SlFormatNumber, SlInput } from '@shoelace-style/shoelace/dist/react';

const App = () => {
  const [value, setValue] = useState(1000);

  return (
    <>
      <SlFormatNumber value={value} />
      <br />
      <br />
      <SlInput
        type="number"
        value={value}
        label="Number to Format"
        style={{ maxWidth: '180px' }}
        onSlInput={event => setValue(event.target.value)}
      />
    </>
  );
};

Examples

To get the value as a percent, set the type attribute to percent.

<sl-format-number type="percent" value="0"></sl-format-number><br />
<sl-format-number type="percent" value="0.25"></sl-format-number><br />
<sl-format-number type="percent" value="0.50"></sl-format-number><br />
<sl-format-number type="percent" value="0.75"></sl-format-number><br />
<sl-format-number type="percent" value="1"></sl-format-number>

import { SlFormatNumber } from '@shoelace-style/shoelace/dist/react';

const App = () => (
  <>
    <SlFormatNumber type="percent" value={0} />
    <br />
    <SlFormatNumber type="percent" value={0.25} />
    <br />
    <SlFormatNumber type="percent" value={0.5} />
    <br />
    <SlFormatNumber type="percent" value={0.75} />
    <br />
    <SlFormatNumber type="percent" value={1} />
  </>
);
