ProFormDigit 怎么搞负数呀？
官网只给出了
与 [inputNumber](https://ant.design/components/input-number-cn/) 相同。它自带了一个格式化 (保留 2 位小数，最小值为 0)，有需要你可以关掉它。
但是没说怎么关掉~~~

Start with the ProFormDigit documentation and the linked Ant Design InputNumber documentation. Determine how the built-in two-decimal formatter and minimum value of zero can be disabled or overridden, then document the negative-number configuration. Done means the page clearly explains how to allow negative values.
