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

\ctxlua{text.sprint(string.format("0.3\%f",sqrt(2)))} or \ctxlua{text.sprint(string.format("0.3\letterpercent f",sqrt(2)))} Wolfgang
