Dear List,

Me again,

I have a question to this formula. I want to use 0.222 222 222_3, but I get 0.222222222_3. And another question too: how can I say, that I want not so much place between formula lines?

\setuppapersize[A4] \setupbodyfont[thermes, 8pt] \starttext \startformula x_1 = 0.222 222 222_3 \stopformula

\stoptext

I want to have

\startformula x_1= 0.222 222 222 x_1=0.222 222 222 \stopformula ,

but not

\startformula a=b

a=b \stopformula

Many thanks for your help and tips.

1. Math mode has its own rules regarding spaces. 2. Use \digits to format the number. 3. Use \startalign or \startmathalignment to align multiple lines in a formula. %%%% begin example \setdigitmode{4} \starttext \startformula \startmathalignment[align={1:right,2:left}] \NC x_1 \EQ \digits{0.222,222,222}_3 \NR \NC x_1 \EQ \digits{0.222,222,222}_3 \NR \stopmathalignment \stopformula \stoptext %%%% end example For more information about math look into the mathincontext manual.

Hi Ursula, two comments on your code (once Wolfgang solved all issues):

\setuppapersize[A4]

Portrait A4 is the default in ConTeXt (unless I have been missing something for decades).

\setupbodyfont[thermes, 8pt]

The font for Times is termes or times (using TeX Gyre Termes). I hope it helps, Pablo
