since 0.14.0. This will now raise a ``TypeError``, see :ref:`here <whatsnew_0180.enhancements.float_indexers>`.

Formatting of integer in FloatIndex
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

Integers in ``FloatIndex``, e.g. 1., are now formatted with a decimal point
and a ``0`` digit, e.g. ``1.0`` (:issue:`11713`)

This change affects the display in jupyter, but also the output of IO methods
like ``.to_csv`` or ``.to_html``
