Module:Simplified fraction

Module documentation[view] [edit] [history] [purge]

This module implements a template that is currently missing or does not use this module. (edit template)

This module automatically creates a fraction in simplest form from a numerator and denominator. Whether the fraction is in a mixed form or not when greater than 1 can be controlled using the mixed parameter.
