.. admonition:: ``FloatField`` vs. ``DecimalField``



    The :class:`FloatField` class is sometimes mixed up with the

    :class:`DecimalField` class. Although they both represent real numbers, they

    represent those numbers differently. ``FloatField`` uses Python's ``float``

    type internally, while ``DecimalField`` uses Python's ``Decimal`` type. For

    information on the difference between the two, see Python's documentation on

    `Decimal fixed point and floating point arithmetic`_.
