Re: [NTG-context] How to reset numbers of formulas?

Is it possible to reset the numbers which appear after invoking \placeformula?

To be more precise, I mean the following situation:

\starttext

Euler says \placeformula \startformula {\rm e}^{{\rm i} \pi} + 1 = 0. \stopformula The above formula will have number (1). Euler's formula is the same as the following \placeformula \startformula {\rm e}^{{\rm i} \pi} = - 1. \stopformula The above formula will have number (2), but for some reasons I wish to number it again as (1). \stoptext

I would like to have a solution which works with ConTeXt mkiv.

Thanks for any advice, and best regards: OK

\resetnumber[formula] or \setnumber[formula]{<insert number>}
