Adds @danielafcarey fix

numbers.py

from django import template

register = template.Library()


@register.filter
def cool_number(value, num_decimals=2):
    """
    Django template filter to convert regular numbers to a
    cool format (ie: 2K, 434.4K, 33M...)

    :param value: number
    :param num_decimals: Number of decimal digits
    """

    int_value = int(value)
    formatted_number = '{{:.{}f}}'.format(num_decimals)
    if int_value < 1000:
        return str(int_value)
    elif int_value < 1000000:
        return formatted_number.format(int_value/1000.0).rstrip('0').rstrip('.') + 'K'
    else:
        return formatted_number.format(int_value/1000000.0).rstrip('0').rstrip('.') + 'M'

Please how do I use it in my template? Thanks

@danielafcarey Thanks for your correction!

@dantechplc Checkout Django's docs about custom filters (https://docs.djangoproject.com/en/3.2/howto/custom-template-tags/). You need to add this file inside templatetags folder within your django app directory as it says in the docs. After that you can load that custom filter in your template and use it:

{% load numbers %}

...

{{ yourvar|cool_number }}
