How do I display a rounded version of a number in my Django/Python template?

I'm using Django and Python 3.7. In my template I have this

{{ round(articlestat.votes) }}

which results in teh error

Could not parse the remainder: '(articlestat.votes)' from 'round(articlestat.votes)'

Is there a way to display a rounded version of my number without creating an additional @property method in the model? It just seems like overkill to do a method every time I want the data formatted a little differently.

#python #django
