``value``     Template                          Output

``34.23234``  ``{{ value|floatformat:"0" }}``   ``34``

``34.00000``  ``{{ value|floatformat:"0" }}``   ``34``

``39.56000``  ``{{ value|floatformat:"0" }}``   ``40``

Using ``floatformat`` with no argument is equivalent to using ``floatformat``

with an argument of ``-1``.
