Bug: NumberField calls onChange with NaN when the field gets emptied

[marcopiii]

Description of the bug

When a NumberField gets emptied, the component calls the onChange function passing NaN as argument.

I would expect it to pass null or undefined: it would be way easier to handle such cases since it would be visible in the callback signature.
