Re: [NTG-context] mathfun

Hi Hans, Thanks for the new features you have introduced in the module mathfun. Actually I have been using commands such as the one mentioned by Aditya, \ctxlua{myfunction(args)} but for the formatting of the output, that is when one wants only 3 or four decimal digits, that approach is not very handy. So I will use the new feature and I’ll put it on the wiki once I have a few interesting examples. By the way, what does \complexexpr{123 + new(456,789)} mean? Best regards: Otared

I uploaded an lmtx update (only m-mathfun added).

Attached a short description of this (windy stormy friday afternoon) math experiment. The question is, what similar features using this trickery come to mind. Personally, I can see occasionally making use of this instead of \ctxlua{myfunction(args)}. There is a similar library called pgfmath which is part of the tikz package, which is used quite heavily by the pgfplots package but also appears to be popular for other purposes: https://tex.stackexchange.com/questions/tagged/pgfmath?tab=Votes I guessed right that you would be the first to to react! Anyway, I suppose that you come up with additional demands like:

\permanent\protected\def\randomized{\thewithproperty\plustwo}

so that we can do:

$ \sin(x) = \randomized\sin{2pi} $

which i'm sure you can figure out by looking at the source.
