@Vaibhav Mishra,

Does it work for you? https://docs.djangoproject.com/en/3.0/ref/templates/builtins/#add

Like: {% value|add:"0" %}

If it does not work for you: then create a custom template filter and register it:

YOUR_APP_FOLDER/
__init__.py
models.py
templatetags/
    __init__.py
    your_app_name_extras.py [any valid filename.py]
views.py

in your_app_name_extras.py

from django import template
register = template.Library()

@register.filter()
def to_int(value):
   return int(value)

In your template file, you need to put the code:

{% load your_app_name_extras %}
 {{ value|to_int }}
