Is it possible to number sections by binary numbers, starting at 0? So section{First Section} would render as "0. First Section", and the next instance would render "1. Second Section" and the third, "10. Third Section"?

Sure.

documentclass{article}



usepackage{expl3}



ExplSyntaxOn

    cs_set:Npn thesection {int_to_bin:n{value{section}-1}}

ExplSyntaxOff



begin{document}



section{one}



section{two}



section{three}



end{document}

Note that I only changed the displayed number here, so the section counter still has the value 1 for the first section, we only print 0. If you want the section to "really" have the number 0, you need to remove the -1 from the definition of thesection and set the counter to -1 at the start of the document.

The fmtcount package provides a simple way to get the binary numbers. To begin counting at zero you need to set the section counter initially to -1. You can also pad the values with zeroes if you wish.

documentclass{article}

usepackage{fmtcount}

renewcommand{thesection}{binary{section}.}

setcounter{section}{-1}% To begin at 0



begin{document}



section{First section}

section{Second section}

section{Third section}

section{Fourth section}

section{Fifth section}

renewcommand{thesection}{padzeroes[4]binary{section}}

setcounter{section}{-1}

section{First section}

section{Second section}

section{Third section}

section{Fourth section}

section{Fifth section}

end{document}
