I added this on to the change I just made to derivsecant to allow extended
precision.

Hi,
Sorry for coming in late ... While editing calculus.ijs, could someone
please replace ". by (0!:100) at line 102?
That allows pderiv_jcalculus_ to handle multi-line verbs (user's
functions), as suggested by Raul in
https://www.jsoftware.com/pipermail/beta/2019-October/009456.html .
Thanks,
Assuming what I can now see is the latest version, line 174 still looks wrong:
if. coeffs=. -: '' do. '0&p.' return.
should be
if. coeffs -: '' do. '0&p.' return.
... but perhaps that’s already been done in another incarnation.
Cheers,
Mike

Mike, thanks. I noticed I missed that out too.
I have added fexp and merged.

Thanks Chris.
You are correct, I forgot to add a verb, fexp, which is needed. I have added it
and merged.
Thanks,

For interest, I had a look at the changes in the script.
I tried both derivatives, and both failed in different ways:
a) polynomials using p. :
(1 2 3 & p. ) deriv 1 NB. result should be 2 6&p.
0&p.
(0 & p. ) deriv 1 NB. ok!
0&p.
b) f() ^ h()

I have merged in your pull request and added you to the math/calculus
repository.
I got an error when trying the following. Should this work now?

Thanks.
Thanks for the reply.
I am still not entirely sure how to get authorized to edit the github
repository for calculus. Perhaps I should just request access from Chris Burke?
Thanks,

I wrote a bug report and fix in the source chat a couple of weeks ago. There
was no response, so I guess I wrote in the wrong chat.
The calculus addon script has one glaring issue, and one small issue with an
easy fix.
The glaring issue is the inability to differentiate the constant zero functi
