\ProvidesPackage{mkessler-faktor}[2022/01/15 - Faktor package that also handles cofaktors]
|
|
|
|
|
|
|
|
% Extension the faktor package for
|
|
% - cofaktor command that provides A \ B notation
|
|
% - scaling the / in the middle
|
|
% - fine positioning of enumerator / denominator
|
|
|
|
% This is essentially taken from the stackexchange question found at
|
|
% https://tex.stackexchange.com/questions/27591/extending-the-faktor-package

% and answered by 'Werner' (https://tex.stackexchange.com/users/5764/werner)
