=== mathexpr with LMTX ===
In LMTX there is a new way to use calculated expressions with mathexpr through ([https://github.com/contextgarden/context-mirror/blob/7fd782dace8f90e7e032ca8f449f8ca4eada450b/doc/context/sources/general/manuals/math/math-fun.tex math-fun]).
Some examples are:
<texcode>
$ \pi = \mathexpr[.40N]{pi} $
$ \pi = \mathexpr[.80N]{sqrt(11)} $
$ \pi = \decimalexpr[.80N]{sqrt(11)} $
$ \pi = \decimalexpr{sqrt(11)} $
$ c = \complexexpr{123 + new(456,789)} $
</texcode>
