Hello Andreas,
Just a quick hack:
\usemodule[calcmath]
\startluacode
sqrt = math.sqrt
pi = math.pi
function my_equation(s, r)
r = tostring(r)
tex.print(s:gsub("*", "×") .. "=" .. r:gsub("%.", ","))
end
\stopluacode
\def\calculate#1{\calcmath{\ctxlua{my_equation("#1", #1)}}}
\starttext
\startlines
\calculate{1+2}
\calculate{3/2-1}
\calculate{3*2}
\calculate{sqrt(2)}
\calculate{2*pi}
\stoplines
\stoptext
Cheers, Peter
