--- order: 3 title: zh-CN: 高精度小数 en-US: High precision decimals --- ## 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'; function onChange(value: string) { console.log('changed', value); } export default () => ( style={{ width: 200 }} defaultValue="1" min="0" max="10" step="0.00000000000001" onChange={onChange} stringMode /> ); ```
