python - Restrict django FloatField to 2 decimal places

Question

I am looking for a way to limit the FloatField in Django to 2 decimal places has anyone got a clue of how this could be done without having to use a DecimalField.

I tried decimal_places=2but this was just giving me a migration error within the float field so i am thinking this method must only work within DecimalFields.

If you are only concerned with how your FloatField appears in forms, you can use the template filter floatformat.

From the Django Docs:

If used with a numeric integer argument, floatformat rounds a number to that many decimal places.

For example, if value = 34.23234, then in your template:

{{ value|floatformat:2 }}  # outputs 34.23
