Describe the Bug

As seen in the screenshots, I'm using the FormControl tag which is using an InputNumber accepter which should store the values I input as numbers, but instead, is stored as string. When the callback onChange is called in the form <Form onChange={callback} ...> the value of this field (i.e this FormControl) returns a string instead of a number.

Expected Behavior

The value for each FormControl should be stored with the most representative javascript type. So, if my FormControl has an InputNumber accepter, I would expect that the value stored is a number, not a string.

To Reproduce

I'll later update this issue including how to reproduce it

If it returns a number, InputNumber will not be able to support decimals.

For example, if we need to manually enter 1.5, the onChange event will be triggered every time the input is made. When the string 1. is entered, it is forced to be a number, and 1. becomes 1.

So we hope you can customize the processing data type in the onChange callback of InputNumber.
