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)

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
