This snippet allows you to use a new field type, RoundedDecimalField, that will automatically round any value affected to it according to the max_digits and decimal_places attributes. You will no longer receive validation errors if you use a float or a decimal with too many decimal digits.
Fixed-point model field based on `IntegerField` and `DecimalField`. Represented as `Decimal` in Python for accurate calculations, stored as integer in the database. Configurable decimal places, defaults to 2.
Converts an integer or floating-point number or a string to a string containing the delimiter character (default comma) after every delimeter_count digits (by default 3 digits)
Template filter to format a number so that it's thousands are separated by commas. {{ number|format_thousands }}
Python json module or simplejson don't support Decimals out of the box. Here's an encoder that casts Decimals into floats and then displays them in desired format.
The BooleanField and DecimalField `elif` blocks are only included in this snippet to give context in the admin_list.py. Insert the CurrencyField block into the file and the Currency fields will display properly in record lists. If you have all of the objects ( [Currency Object](http://www.djangosnippets.org/snippets/1525/), [Currency Widget](http://www.djangosnippets.org/snippets/1526/), [Currency Form Field](http://www.djangosnippets.org/snippets/1527/), and the [Currency DB Field](http://www.djangosnippets.org/snippets/1528/) ) then all you have to do is use the DB Field object and the Admin app will (should) work properly. Please let me know if you have any problems.
This is an extension of the DecimalField database field that uses my [Currency Object](http://www.djangosnippets.org/snippets/1525/), [Currency Widget](http://www.djangosnippets.org/snippets/1526/), and [Currency Form Field](http://www.djangosnippets.org/snippets/1527/). I placed my Currency object in the Django\\utils directory, the widget in Django\\froms\\widgets_special.py, and the form field in Django\\forms\\fields_special.py because I integrated this set of currency objects into the Admin app ( [here](http://www.djangosnippets.org/snippets/1529/) ) and it was just easier to have everything within Django. UPDATE 08-18-2009: Added 'import decimal' and modified to_python slightly.

This is an extension of the DecimalField form field that uses my [Currency Object](http://www.djangosnippets.org/snippets/1525/) and [Currency Widget](http://www.djangosnippets.org/snippets/1526/).

UPDATE 07-30-2009: Add the parse_string argument to properly test the string format as per the update to the [Currency Object](http://www.djangosnippets.org/snippets/1525/) UPDATE 09-15-2009: Properly handle None's in the clean method The rest of the series: [Currency Object](http://www.djangosnippets.org/snippets/1525/), [Currency Widget](http://www.djangosnippets.org/snippets/1526/), [Currency DB Field](http://www.djangosnippets.org/snippets/1528/), [Admin Integration](http://www.djangosnippets.org/snippets/1529/)
This is a simple TextInput widget that uses my [Currency object](http://www.djangosnippets.org/snippets/1525/). I placed my Currency object in the Django utils directory because I integrated a set of currency objects into the Admin app ( [here](http://www.djangosnippets.org/snippets/1529/) ) and it was just easier to have everything within Django.

This object stitches together the [Babel](http://babel.edgewall.org/) number formating and the Decimal object, with a little of my own hand rolled validation for parsing. Note the comment at the end of the code. It contains two lines to add to your settings.py. CURRENCY_LANGUAGE_CODE = 'pt_BR' CURRENCY_CODE = '' # If one exists like 'USD', 'EUR' UPDATE 06-03-2009: Now with rounding UPDATE 07-14-2009: Now with - More graceful handling of missing settings variables - Support for negatives (small oversight) - More flexible format strings - Thorough doctest tests UPDATE 07-30-2009: Added the parse_string argument to the `__new__()` method. This fixes a bug when importing data using `manage.py loaddata`. I have not yet updated the tests to reflect the change.

Takes a float number (23.456) and uses the decimal.quantize to round it to a fixed exponent. This allows you to specify the exponent precision, along with the rounding method. And is perfect for monetary formatting taking into account precision.
Tuned IPAddressField with IPv4 & IPv6 support
Simple DecimalField class extension that automatically adds formatting and validation for comma-separated "decimals". Works wonderfully for price fields. Could be extended to strip dollar signs or to be locale-agnostic.
This might be handy in countries where decimals are entered with a comma separating the decimal places from the integer part (for instance in Germany). It lets user enter and displays all decimals with a comma separator. I ran into this problem and couldn't find a clean internationalized way of doing it... but newforms makes it so easy to roll your own. Hope it helps someone.
