Bug in placeformula

Bug in placeformula

[Otared Kavian via ntg-context]

Dear Hans, dear Mikael,

In my experiments with the new math engine, I noticed that there is an issue with \placeformula when one sets the location of the numbers on the left: the number is one line above the formula. Here is a minimal example:

% begin bug-placeformula-left.tex
\setupformulas[location=left]

\starttext

\placeformula
\startformula
a^2 + b^2 = c^2.
\stopformula

\stoptext
% end bug-placeformula-left.tex

Moreover, in some environments (such as enumerations) the bug destroys completely the flow of text but I could not set up a minimal example to send you.

Best regards: Otared

Thanks for reporting! We must have missed this one while testing. It
should be fixed.

If you for the moment can live without splitting, then this seems to
give you the formula number where expected:

\placeformula
\startformula[location=left,split=no,numberlocation=overlay]
a^2 + b^2 = c^2.
\stopformula

(or put the keys in \setupformula)

I hope it helps.

Hi Mikael,

Thank you for your reply. For the time being I am not in a hurry to solve the issue with placeformula (when the numbers are on the right, there is no problem…).

Best regards: Otared

Hi Henri,

Your are right there is an issue with \startmathcases…\stopmathcases: the equations are not numbered when using this structure.
As a temporary solution you can use \startmatrix…\stopmatrix as in the following, or you can define your own \startalignedcases.

\starttext

\placeformula
\startformula
f(\mu,t) := 
\startmatrix[left={\left\{\,},right={\right.}]
   \NC 0 \NC \mu > 2t \NR
   \NC \pi/2 \NC \mu = 2t \NR
   \NC \pi \NC \mu < 2t \NR
\stopmatrix
\stopformula

\stoptext

Best regards: OK

Dear list,

this formula is not numbered even though it should be.  Please fix.

\starttext
\placeformula
\startformula
  \startmathcases
    \NC 0 \NC $\mu > 2t$ \NR
    \NC \pi/2 \NC $\mu = 2t$ \NR
    \NC \pi \NC $\mu < 2t$ \NR
  \stopmathcases
\stopformula
\stoptext

Cheers, Henri
