Easy way to sectioning with a leading zero

Question

There is a easy way to modify only this command

\renewcommand\thesection{\arabic{section}.}

in order to have an arabic counter with just one leading zero instead the original arabic without leading zero?

you mean like this\renewcommand\thesection{\ifnum\value{section}<10\relax0\fi\arabic{section}} — touhami, Jun 16 '16 at 11:55
@touhami Better a space between 10 and 0 than \relax, so as to preserve full expandability. — egreg, Jun 16 '16 at 11:58
Yes but there is something that give me an error. I think is ''\value'' do you know why? @touhami — Andrea Leo, Jun 16 '16 at 12:04
can you please add a minimal example that produce the error? for me it works fine. — touhami, Jun 16 '16 at 12:09
I need some package in order to use '' \value ''? LaTeX don't find that command — Andrea Leo, Jun 16 '16 at 13:15
@touhami I think that I found the problem your command not work with one of my essential package that put the accents
\usepackage[utf8]{inputenc} — Andrea Leo, Jun 16 '16 at 18:33
no way! try again with \renewcommand\thesection{\ifnum\value{section}<10 0\fi\arabic{section}} or type it your self, don't copy paste — touhami, Jun 16 '16 at 19:00
@AndreaLeo: \value is a LaTeX command -- it must be defined! — , Jun 16 '16 at 20:12

This small document adds a leading zero in front of the section number and uses 15 dummy \blinddocument commands in the loop to fill up.

\documentclass{article}


\usepackage{blindtext}
\makeatletter
\let\latex@@thesection\thesection
\newcommand{\padwithzero}{%
  0%
}%
\renewcommand{\thesection}{\ifnum\c@section<10\relax\padwithzero\fi\latex@@thesection}
\newcount\dummycntr
\makeatother
\begin{document}
\tableofcontents

\loop\unless\ifnum\dummycntr=15
\begingroup
\blinddocument
\endgroup
\advance\dummycntr by 1
\repeat
\end{document}
