No, as context() is already built in for quite a while and I don't want
to polute the global namespace any more that it already is.
Also, there is no printf in lua and I see no reason to mimick c calls
(for me printf does not feel more natural).

With the format "%..." it's better to call something like
\clxluacode{contextf()} ? (like print() & printf())

we can consider adding

i'll add this but keep in mind that this will only work in the text

Ahhh, forgot to escape %, my bad !!!
The code \ctxlua{tex.print(string.format("\%0.2f",355/14))} works ok for me.

[NTG-context] LuaTeX & printf() function ?
Hi,
Here is my test:
===
\setuppapersize[A4][A4]
\usetypescript[postscript]
\setupbodyfont[palatino,12pt]
\starttext
\startformula
K = \frac{\sigma_1}{\sigma_2} = \frac{355}{14}= \ctxlua{tex.print(355/14)}
\stopformula
\stoptext
===
It works well and give me result = 25,357142857143. In order to obtain
2 decimal number I tried:
\startformula
K = \frac{\sigma_1}{\sigma_2} = \frac{355}{14}=
\ctxlua{tex.printf("%0.2f",355/14)}
\stopformula
But it does not work. Here is the error:
tex.printf("\doplaceformulanumber \stopdisplaymath \global \let \gdef \ETC.
! File ended while scanning text of \zerocount.
}
<*> ./test-lua.tex
?
Another try:
\startformula
K = \frac{\sigma_1}{\sigma_2} = \frac{355}{14}=
\ctxlua{tex.print(string.format("%0.2f",355/14))}
\stopformula
gives me the same error.
So is there really a function printf() in LuaTeX engine ?
Thanks
