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

\ctxlua{text.sprint(string.format("0.3\%f",sqrt(2)))} or \ctxlua{text.sprint(string.format("0.3\letterpercent f",sqrt(2)))} Wolfgang
Hi Jorge, Regarding your first question try this: \starttext The square root of 2 is \ctxlua{tex.print(math.sqrt(2))}\dots, but usually the default value \ctxlua{tex.print(math.floor(1000*math.sqrt(2))/1000)} is considered to be a good approximation. \stoptext (There is also math.ceil) Best regards: OK On 24 oct. 2009, at 18:59, batela wrote:
