<div dir="ltr"><div dir="ltr">I am far (very far!) from being a tex expert ... but could you not use a 2ndary program to do the calculations and format them into something tex understands and then \include that result into the main tex/latex/latex2html files? Wrap it all together in a makefile and you're done. Much easier, thinks I, than writing a pre-processor :)<br></div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Fri, Apr 5, 2019 at 9:35 AM <<a href="mailto:bmassing@cs.trinity.edu">bmassing@cs.trinity.edu</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex">First, I agree that it doesn't seem feasible for latex2html to <br>
implement all of TeX.<br>
<br>
Below is a short simple program showing my current macros and<br>
usage. I wrote the macros a long time ago, and on looking at<br>
them again, they're kind of ugly. But they get the job done --<br>
as long as I only want to use integers. That's starting to <br>
feel restrictive.<br>
<br>
There are various options for doing arithmetic on floating-point<br>
values, including what seem to be a variety of LaTeX packages.<br>
It occurs to me, however, that very likely none of them will do<br>
what I want to, *because* I want to be able to print the total<br>
at the top of the document. My current macros can do that using<br>
\refstepcounter and \label, but I don't think any of the LaTeX<br>
packages I've looked at would do that.<br>
<br>
More and more I think I need to just write a preprocessor! "How<br>
hard can it be" .... :-)?<br>
