How can I use math.log10 function with the directlua?














0















I would like to know how I can use math.log10 function with the directlua, because I always get none from directlua.



Following a minimal example:



%Engine: LuaLaTeX;
%Encoding: UTF-8;



documentclass[11pt,A4paper]{article}



begin{document}
{centering Function $log$ - Examplepar}



noindentdirectlua{tex.print(math.log(math.exp(1)))} is the natural logarithm
of $e$.
directlua{tex.print(math.log10(100))} is the base-10 logarithm of 100.
textbf{What is the mistake in the last sentence?}



end{document}
