Graphics, Figures & Tables ⇒ Automatic Calculation of Week Number in Table

[Stefan Kottwitz]

Just a remark, in the example babel was called without language option, which prevents compilation. I just noticed it when I used the convenient online compiler option (well, the mentioned slashbox too).

Arrrh, yes. Initially, I parsed the language option the \documentclass but then removed it again and forgot to parse it to babel.

I am not sure how to combine the two solution, in order to get yours but with week numbers modulo 52.

I haven't wuite understoof what you exactly want to calculate how. (maybe I'm too tired and should go to bed...) Can you give me a pseudo-code example?

Can you give me a pseudo-code example?

Sure!

Pseudo input:

Code: Select all

\documentclass{article}

\newcounter{week}
\setcounter{week}{49}

\newcommand\week[1]{Week~<CODE>}

\begin{document}

\begin{tabular}{lccccc}
 & \week{1} & \week{2} & \week{3} & \week{4} & \week{5} \\
 & \week{2} & \week{3} & \week{4} & \week{5} & \week{1} \\
 & \week{3} & \week{4} & \week{5} & \week{1} & \week{2} \\
 & \week{4} & \week{5} & \week{1} & \week{2} & \week{3} \\
 & \week{5} & \week{1} & \week{2} & \week{2} & \week{4}
\end{tabular}

\end{document}

Output:

Code: Select all

Week 49  Week 50  Week 51  Week 52  Week 1
Week 50  Week 51  Week 52  Week 1   Week 49
Week 51  Week 52  Week 1   Week 49  Week 50
Week 52  Week 1   Week 49  Week 50  Week 51
Week 1   Week 49  Week 50  Week 51  Week 52

Even better if the numbers can be aligned after the first decimal, i.e.,

Code: Select all

52
 1

but that is by no means important at all.

[cgnieder]

Ah, ok. Pretty straight forward, I would think:

Code: Select all

\documentclass{article}

\newcounter{week}
\setcounter{week}{49}

% \modulo by @egreg (http://tex.stackexchange.com/a/34449/5049)
\def\truncdiv#1#2{((#1-(#2-1)/2)/#2)}
\def\moduloop#1#2{(#1-\truncdiv{#1}{#2}*#2)}
\def\modulo#1#2{\number\numexpr\moduloop{#1}{#2}\relax}

\def\weeknum#1{\the\numexpr\modulo{#1+\value{week}-1}{52}\relax}

\newcommand\week[1]{week~\ifnum\weeknum{#1}=0\relax52\else\weeknum{#1}\fi}

\begin{document}

\begin{tabular}{lccccc}
 & \week{1} & \week{2} & \week{3} & \week{4} & \week{5} \\
 & \week{2} & \week{3} & \week{4} & \week{5} & \week{1} \\
 & \week{3} & \week{4} & \week{5} & \week{1} & \week{2} \\
 & \week{4} & \week{5} & \week{1} & \week{2} & \week{3} \\
 & \week{5} & \week{1} & \week{2} & \week{3} & \week{4}
\end{tabular}

\end{document}

Spot on!

Thank you very much, Clemens.
