Documentation example request for InputNumber with comma as decimal separator.

[stumps-dev]

• I have searched the issues of this repository and believe that this is not a duplicate.

What problem does this feature solve?

I needed InputNumber component to use comma as decimal separator, I searched answers on Google, and you guys basically said it's not possible.
It took way too long for me to find out how to do this, it would be nice if these examples could be added to the docs to save other developers some time with this problem.

What does the proposed API look like?

These InputNumber components should behave exactly like a normal InputNumber component but with a comma as decimal separator.

Regular InputNumber:

const inputRef = React.createRef()

<InputNumber
  ref={inputRef}
  formatter={value => value.toString().replace('.', ',')}
  parser={input => input.replace(/[^\w\,-]+/g, '')}
  onChange={value => {
    value = parseFloat(value.toString().replace(',', '.'))
    inputRef.current.inputNumberRef.setState({ value })

    //Do something with 'value'
  }}
/>

As a form Item:

<Form.Item>
  {getFieldDecorator('fieldName', {
    normalize: value => {
      if (value || value == 0)
        if (value.toString().match(/\d+,($|\d+)/))
          return value.toString().replace(',', '.')
        else
          return value
    }
  })(
    <InputNumber
      formatter={value => value.toString().replace('.', ',')}
      parser={input => input.replace(/[^\w\,-]+/g, '')}
    />
  )}
</Form.Item>
