Store four decimal places but show two in Django admin form

Question

Is it possible to store in my models decimal fields with four decimal places but to show only two in Django admin forms.

class MyModel(models.Model):
    purchase_price_gross = models.DecimalField(
        'Purchase price (gross)', validators=[MinValueValidator(0.0)], 
    max_digits=19, decimal_places=4)

Now in the Admin form the field is showing with 4 decimal places. But how can I restrict the forms to show only two places?

What you want is floatformat: https://docs.djangoproject.com/en/dev/ref/templates/builtins/#floatformat

    {{ value|floatformat }}

So you could edit the admin view to use that, which is covered here:

Just in terms of Django best practices though, it seems like you might be pushing the admin view further than you maybe should, and you should build a custom view?
