# Siunitx does not format numbers [closed]

This is my code for the table, I was expecting siunitx to add the comma to the numebers with more than 3 digits, i.e., 3456 -> 3,456 but it does not happen, the numebers without decimals are shown as they are. I tried some code found in answers in this site that works for people but not for me. Any help?

 \usepackage{siunitx}
\sisetup{group-separator={,},group-minimum-digits={3},output-decimal-marker={.}}

\begin{table}
\centerfloat
\caption{Descriptive statistics of Expedia and Tripadvisor datasets.}
\label{tab:stats}
\scalebox{1}{
\begin{tabular}{l S S}
\hline
\hline
Total Hotels & 5356 & 3701 \\

Average Reviews per Hotel & 68.3 & 154.93 \\

• Welcome to TeX.SX! Please make your code compilable (if possible), or at least complete it with \documentclass{...}, the required \usepackage's, \begin{document}, and \end{document}. That may seem tedious to you, but think of the extra work it represents for TeX.SX users willing to give you a hand.

• The siunitx-package will only format numbers in the \num{}-command. – René B. Christensen Oct 9 '14 at 16:11
• this is not what I understood. For example here tex.stackexchange.com/questions/121387/… look at the first answer. That is what I want but the example does not work for me. – user63979 Oct 9 '14 at 16:39
• This is 'works for me': can you add \listfiles to your input and report the version information this adds to your .log file? – Joseph Wright Oct 9 '14 at 21:12
• @user63979: I stand corrected. I just tried compiling your document, and your current code seems to work on my machine (at least in the memoir document class). – René B. Christensen Oct 10 '14 at 14:15
