应该只是 文档 有问题，具体使用没问题的

不是的，是启动开发模式没问题，构建过后的就有问题。

我发现是因为 https://github.com/vueComponent/ant-design-vue/blob/next/components/vc-input-number/src/index.js#L280 这里的

this.setState({
    focused: true,
});

没有生效，导致 onChange 里面 this.inputting 状态没生效，然后导致后面一直不停格式化。应该是 focus 事件的时机问题

开发模式无法重现这个问题，生产模式运行就会有问题

@tangjinzhou 这个确实是Bug呀，而且还挺严重，用户不可能在开发模式用

目前临时这样修复了一下
