[NTG-context] Curiosity about math.random in LuaTeX

Hi all, This is a curiosity question about the function math.random coming from Lua and used in mkiv: if I typeset the following test file in mkiv, no matter when nor how many times, the sequence of numbers which are output are the same… %%% begin test-random.tex \starttext \dorecurse{25}{% \ctxlua{tex.print(math.random(110,150))} \qquad \ctxlua{tex.print(math.random(math.random(110,120),math.random(140,150)))} \par} \stoptext %%% end test-random.tex Indeed I guess that this is due to the random seed used by LuaTeX: is it possible to force a new random seed upon each typesetting? Thanks for your attention: OK
