numberformat.format() incorrectly formats large/tiny floats in scientific notation
For floats with values larger than 1e16 or smaller than 1e-5, their string representation uses scientific notation in Python, which causes numberformat.format to return an erroneous output.
>>> from django.utils.numberformat import format
>>> format(0.0000000000000000009, '.', 2)
'9e-19.00'
>>> format(1e16, '.', 2, thousand_sep=',', grouping=3, force_grouping=True)
'1e,+16.00'
This is similar to #23935 but that was only fixed for Decimal types.
