## 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。

## 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 >
);
```
