## zh-CN
通过 `formatter` 格式化数字,以展示具有具体含义的数据,往往需要配合 `parser` 一起使用。
> 这里有一个更复杂的货币格式化输入框:[https://codesandbox.io/s/currency-wrapper-antd-input-3ynzo](https://codesandbox.io/s/currency-wrapper-antd-input-3ynzo)
## en-US
Display value within it's situation with `formatter`, and we usually use `parser` at the same time.
> Here is a Intl.NumberFormat InputNumber implementation: [https://codesandbox.io/s/currency-wrapper-antd-input-3ynzo](https://codesandbox.io/s/currency-wrapper-antd-input-3ynzo)
```jsx
import { InputNumber, Space } from 'antd';
function onChange(value) {
console.log('changed', value);
}
export default () => (
<Space>
<InputNumber
defaultValue={1000}
formatter={value => `$ ${value}`.replace(/\B(?=(\d{3})+(?!\d))/g, ',')}
parser={value => value.replace(/\$\s?|(,*)/g, '')}
onChange={onChange}
/>
<InputNumber
defaultValue={100}
min={0}
max={100}
formatter={value => `${value}%`}
parser={value => value.replace('%', '')}
onChange={onChange}
/>
</Space>
);
```
