Hi all!
I played a little bit with LuaTeX in ConTeXt and two questions have arisen.
\usemodule[calcmath]
\starttext
\def\calculate#1{\calcmath{#1=\ctxlua{tex.print(#1)}}}
\calculate{1+2} \par
\calculate{3/2-1}\par % the output should be 0,5
\calculate{3*2}\par
% \calculate{sqrt(2)} \calculate{2*π} % 2*\pi
\stoptext
1) Is it possible to have a comma as decimal separator?
2) If you look at the above definition, it works fine with +, –, /, but not with *. Is it possible to expand my macro that it will also work with a multiplication or even with the last two examples?
Thank you in advance
Andreas
