\begin{abstract}
The \pkg{faktor} package provides a mechanism to produce fractions
for mathematical factors.
Its mechanism is, however, quite limited.
Inspired by the
\href{https://tex.stackexchange.com/}{Tex StackExchange}
answer of user
\href{https://tex.stackexchange.com/users/5764/werner}{Werner},
that was given on
\href{https://tex.stackexchange.com/questions/27591/extending-the-faktor-package}
{https://tex.stackexchange.com/\allowbreak questions/\allowbreak 27591/extending-the-faktor-package}
we provide a simple package that wraps (and slightly modifies)
the given answer into a more general \cs{faktor} command.
\end{abstract}
\begin{function}{\faktor}
\begin{function}{\faktor*}
\begin{syntax}
\cs{faktor}*\oarg{shift enumerator}\marg{enumerator}\oarg{shift denominator}\marg{denominator}
\end{syntax}
Produces a fraction with tilted \enquote{$\diagup$} symbol and the corresponding
\meta{enumerator} and \meta{denominator}.
The \enquote{$\diagup$} symbol is automatically scaled.
The \meta{shift} parameters can be controlled to fine tune the vertical
placement of \meta{enumerator} and \meta{denominator}.
Their default values when not given are \texttt{0.5} and \texttt{-0.5},
respectively.
The \enquote{*} can be optionally given. This will make the \cs{faktor}
behave like the old \cs{faktor} command from the \cs{faktor} package,
that is, the \enquote{$\diagup$} won't scale.
\end{function}
\end{function}
\begin{function}{\cofaktor}
\begin{function}{\cofaktor*}
\begin{syntax}
\cs{faktor}*\oarg{shift denominator}\marg{denominator}\oarg{shift enumerator}\marg{enumerator}
\end{syntax}
Behaves the same as \cs{faktor}, but produces a \cs{cofaktor}.
\end{function}
