Wrap figures and equations

Wrap figures and equations

[Wolfgang Schuster]

Hi Hans,

the following problem is from StackExchange [1] which can only be solved 
by changing
the value of the \c_strc_formulas_mode counter which can’t be the right 
answer for this.

%\unprotected\c_strc_formulas_mode\zerocount

\starttext

\placefigure[right]{}{\blackrule[width=6cm,height=4cm]}
\input ward
\startformula
d = vt
\stopformula
\input ward

\stoptext

[1]

it's more a missing state check ... can you check the beta?

\unexpanded\def\beforedisplayspace
   {.......
    \page_sides_check_floats_indeed} % probably needs more

Hi Hans,

I was going to report a similar issue with \placeformula and floats in general, as in the example below. 
However the trick suggested by Wolfgang does not solve all the problems and in fact in my real size document it triggers an error message saying:

	\strc_formulas_flush_number ...\math_native_reqno 
                                                  {\box \b_strc_formulas_num...
	\strc_formulas_stop_formula ...mulas_flush_number 
                                                  \dostarttagged \t!formulac…

but it is very difficult to set up a minimal example showing this.

In any case here is an example showing the problem with \placeformula and floats, with its PDF attached.

Best regards: OK
