[NTG-context] format float numbers in luatex

24 Oct 2009

      Dear Sirs,

I'm looking a way to format float numbers. For example 
\ctxlua{text.print(sqrt(2))} give me 1.41421356237309504880 but i want 
1.414.

Is there a way to format real numbers.

Note: I had tried  \ctxlua{a = sqrt(a) ; aformat = 
string.format("0.3%f", a) ; text.print(aformat)}

  but that don't work because the  % character

thanks a lot

Have a nice day

jorge
