Fixed #27486 -- Fixed Python 3.7 DeprecationWarning in intword and filesizeformat filters.
intword and filesizeformat passed floats to ngettext() which is deprecated in Python 3.7. The rationale for this warning is documented in BPO-28692: https://bugs.python.org/issue28692. For filesizeformat, the filesize value is expected to be an int -- it fills %d string formatting placeholders. It was likely coerced to a float to ensure floating point division on Python 2. Python 3 always does floating point division, so coerce to an int instead of a float to fix the warning. For intword, the number may contain a decimal component. In English, a decimal component makes the noun plural. A helper function, round_away_from_one(), was added to convert the float to an integer that is appropriate for ngettext().

Django is a high-level Python Web framework that encourages rapid development and clean, pragmatic design. Thanks for checking it out. All documentation is in the "``docs``" directory and online at https://docs.djangoproject.com/en/stable/. If you're just getting started, here's how we recommend you read the docs: * First, read ``docs/intro/install.txt`` for instructions on installing Django. * Next, work through the tutorials in order (``docs/intro/tutorial01.txt``, ``docs/intro/tutorial02.txt``, etc.). * If you want to set up an actual deployment server, read ``docs/howto/deployment/index.txt`` for instructions. * You'll probably want to read through the topical guides (in ``docs/topics``) next; from there you can jump to the HOWTOs (in ``docs/howto``) for specific problems, and check out the reference (``docs/ref``) for gory details. * See ``docs/README`` for instructions on building an HTML version of the docs. Docs are updated rigorously. If you find any problems in the docs, or think they should be clarified in any way, please take 30 seconds to fill out a ticket here: https://code.djangoproject.com/newticket To get more help: * Join the ``#django`` channel on irc.freenode.net. Lots of helpful people hang out there. See https://en.wikipedia.org/wiki/Wikipedia:IRC/Tutorial if you're new to IRC. * Join the django-users mailing list, or read the archives, at https://groups.google.com/group/django-users. To contribute to Django: * Check out https://docs.djangoproject.com/en/dev/internals/contributing/ for information about getting involved. To run Django's test suite: * Follow the instructions in the "Unit tests" section of ``docs/internals/contributing/writing-code/unit-tests.txt``, published online at https://docs.djangoproject.com/en/dev/internals/contributing/writing-code/unit-tests/#running-the-unit-tests
