Django Mathfilters

What is Django Mathfilters?

Django Mathfilters is a reusable Django application that provides easy-to-use math filters for your Django templates. With Django Mathfilters, you can perform simple arithmetic operations, rounding, and formatting of numbers directly in your Django templates.

Features

Django Mathfilters provides several useful filters:

add

The add filter allows you to add two numbers together. For example:

{{ 2|add:3 }}

This will output 5.

subtract

The subtract filter allows you to subtract one number from another. For example:

{{ 5|subtract:3 }}

This will output 2.

multiply

The multiply filter allows you to multiply two numbers together. For example:

{{ 2|multiply:3 }}

This will output 6.

divide

The divide filter allows you to divide one number by another. For example:

{{ 6|divide:3 }}

This will output 2.

modulus

The modulus filter allows you to get the remainder of one number divided by another. For example:

{{ 5|modulus:2 }}

This will output 1.

floor

The floor filter allows you to round down to the nearest integer. For example:

{{ 2.7|floor }}

This will output 2.

ceil

The ceil filter allows you to round up to the nearest integer. For example:

{{ 2.3|ceil }}

This will output 3.

round

The round filter allows you to round to a specified number of decimal places. For example:

{{ 2.3456|round:2 }}

This will output 2.35.

intcomma

The intcomma filter allows you to format a number with commas separating thousands. For example:

{{ 1000000|intcomma }}

This will output 1,000,000.
