I am curious which one would be better fitting as a currency field ? I will do simple operations such as taking difference, the percentage between old and new prices. I plan to keep two digits after the zero (ie 10.50) and majority of the time if these digits are zero, I will be hiding these numbers and display it as "10"
ps: Currency is NOT dollar based :)

The FloatField class is sometimes mixed up with the 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.
FloatField is a floating-point number represented in Python by a float instance. This field is generally used to store huge floating point numbers in the database. The default form widget for this field is a NumberInput when localize is False or TextInput otherwise. Syntax: field_name = models.FloatField(**options)
Now Django does not have a built-in Price Field; however, a field which simulates money in Django can be easily created using the DecimalField. Django's DecimalField requires 2 parameters, one is max_digits and the other is decimal_places. max_digits is the total number of digits that is in the number specified.
Always use DecimalField for money. Even simple operations (addition, subtraction) are not immune to float rounding issues:
>>> 10.50 - 0.20 10.300000000000001 >>> Decimal('10.50') - Decimal('0.20') Decimal('10.30') If you love us? You can donate to us via Paypal or buy me a coffee so we can maintain and grow! Thank you!
