 When you clean a RangeField, and pass it in ('', ''), or (None, None), it
 falls through to the MultiValueField handling, which, when all values are
 empty, treats the cleaned value as empty.

 https://github.com/django/django/blob/master/django/forms/fields.py#L992

 Thus:


 {{{
 FloatRangeField().clean([None, None])
 }}}

 returns `None`, when it really should return FloatRange(None, None).

 There is a very large difference between these.
