django-mathfilters

The django-mathfilters library provides a set of mathematical filters for use in Django templates. These filters allow you to perform simple arithmetic operations, such as addition, subtraction, multiplication, and division, within your templates.

To use django-mathfilters, follow these steps:

1. Install the django-mathfilters library by running the following command in your terminal: pip install django-mathfilters

2. Add 'mathfilters' to the INSTALLED_APPS list in your Django project's settings.py file: python INSTALLED_APPS = [ ... 'mathfilters', ... ]

3. Load the mathfilters in your Django template by adding the following line at the top of your template file: django {% load mathfilters %}

4. Now you can use the mathematical filters in your template. Here are some examples:

5. Addition: django {{ 2|add:3 }} # Output: 5

6. Subtraction: django {{ 5|sub:2 }} # Output: 3

7. Multiplication: django {{ 3|mul:4 }} # Output: 12

8. Division: django {{ 10|div:2 }} # Output: 5.0

9. Floor division (returns the largest integer less than or equal to the result): django {{ 10|floordiv:3 }} # Output: 3

10. Modulo (returns the remainder of the division): django {{ 10|mod:3 }} # Output: 1

11. Exponentiation: django {{ 2|pow:3 }} # Output: 8

These are just a few examples of the mathematical filters provided by django-mathfilters. You can find more filters and their usage in the library's documentation.

Remember to restart your Django server after making any changes to the settings.py file.
