Hi,
In the table below, how to have numbers with only three decimals ?
Thank you.
Fabrice
\starttext
\startluacode
local letters_1 = { "A", "B", "C", "D", "E", "F", "G", "H", "I", "J" }
local letters_2 = { "1", "Année", "1998", "1999", "2000", "2001", "2002",
"2003", "2004", "2005","2006" }
context.startxtable({"align={middle,lohi},
width=1.2cm,offset=0.8ex,bodyfont=9pt"})
context.startxrow({"background=color,backgroundcolor=green"})
context.startxcell({"background=color,backgroundcolor=white,frame=off"})
context("")
context.stopxcell()
for _, letter in ipairs(letters_1) do
context.startxcell()
context(letter) context.stopxcell()
end
context.stopxrow()
context.startxrow()
for _, letter in ipairs(letters_2) do

context.startxrow()
context.startxcell() context("2") context.stopxcell()
context.startxcell({"width=2cm"}) context("Prix (kg)") context.stopxcell()

context.startxcell() context("%0.5g",1.031^i) context.stopxcell()
end

Have you tried
context.startxcell() context("%0.3g",1.031^i) context.stopxcell()
?

Hi Fabrice,
at least in your sample "0.4g" seems the way to go, such as in:
context.startxcell() context("%0.4g",1.031^i) context.stopxcell()
Just in case it might help,
Pablo

better use %0.3f as %g is somewhat unpredictable; using %0.3N will omit
redundant zeros (slower but not relevant here)

Hi,
Thank you for your suggestions, the problem is solved. I searched, but the
solutions seemed too complex. Is it specific to Context with Lua. If so,
which document should you read ?

how do you mean complex ... anyway, if you refer to %g, one problem can
be that the E notation kicks in

Hi Hans,
In fact, I was talking about functions that seemed to me "complicated" for
what I wanted to do.
