< [[Math]] Be sure to also read the recent (2006-08-02) [http://dl.contextgarden.net/myway/mathalign.pdf Using \startalign and friends] written by Aditya Mahajan. This set of math examples is taken from the comments in the <tt>[[source:core-mat.tex|core-mat.tex</tt> ]] file, which contains most of the core ConTeXt math macros. The <tt>textwidth</tt> has been set to 8 cm in these examples so that the page isn't too wide (see [[Layout]] and {{cmd|setuplayout}} for further information specific to layout).

In the next examples we explicitly align formulas to the left (<{{cmd>|raggedleft</cmd>}}), center and right (<{{cmd>|raggedright</cmd>}}):

<texcode>\setupformulas[aligncontext source=left]\startformula c^2 "yes" text= a^2 + b^2 \stopformula"Or in print:">\setupformulassetuplayout[aligntextwidth=middle8cm]\startformula c^2 = a^2 + b^2 \stopformula\setupformulas[align=right]\startformula c^2 = a^2 + b^2 \stopformula</texcode> Or in print: <context>

With formula numbers these formulas look as followsthe code is:

<contextsource="yes" text="And the formulas look like:">\setuplayout[textwidth=8cm]

This was keyed in as: <texcode>\setupformulas[align=left]\placeformula \startformula c^2 = a^2 + b^2 \stopformula\setupformulas[align=middle]\placeformula \startformula c^2 = a^2 + b^2 \stopformula\setupformulas[align=right]\placeformula \startformula c^2 = a^2 + b^2 \stopformula</texcode> When tracing is turned on (<{{cmd>|tracemathtrue</cmd>}}) you can visualize the bounding box of the formula,

<texcode>\setupformulas[strutcontext source="yes]\tracemathtrue\placeformula \startformula c^2 " text= a^2 + b^2 \stopformula</texcode> "This time we get a more spacy result. [Ed.
