zh-CN: 高精度小数

## zh-CN
|
|
|
|
通过 `stringMode` 开启高精度小数支持，`onChange` 事件将返回 string 类型。对于旧版浏览器，你需要 BigInt polyfill。
|
|
|
|
## en-US
|
|
|
|
Use `stringMode` to support high precision decimals support. `onChange` will return string value instead. You need polyfill of BigInt if browser not support.

```tsx
|
|
import { InputNumber } from 'antd';
|
|
import React from 'react';
|
|
|
|
const onChange = (value: string) => {
|
|
console.log('changed', value);
|
|
};
|
|
|
|
const App: React.FC = () => (
|
|
<InputNumber<string>
|
|
style={{ width: 200 }}
|
|
defaultValue="1"
|
|
min="0"
|
|
max="10"
|
|
step="0.00000000000001"
|
|
onChange={onChange}
|
|
stringMode
|
|
/>
|
|
);
|
|
|
|
export default App;
|
|
```
