LaTex produces wrong symbols

[Morris Hirsch]

LaTeX package txfonts interchanges the meaning of the commands in Table 8.16 in ``The Latex
Companion'' (2nd edition) :
\precapprox= prints as \succapprox
\succapprox= prints as \precapprox
These symbols are defined in
    /usr/share/texmf-tetex/tex/latex/txfonts/txfonts.sty
The following LaTex code produces this result:
\documentclass{article}
\usepackage{txfonts}
\begin{document}
\verb=\precapprox= prints as \ \ $\precapprox$
\verb=\succapprox= prints as \ \ $\succapprox$
\end{document}

Note however that LaTex package amssymbols prints these symbols correctly.

Package hint: texlive-base

[Ming Hua (minghua)]

The file mentioned in the report is /usr/share/texmf-tetex/tex/latex/txfonts/txfonts.sty, which belongs to tetex-extra in Debian etch. Why is this bug assigned to texlive-base pacakge?

The teTeX stuff is mostly obsoleted (both in Debian and Ubuntu) anyway. To bug reporter Morris Hirsch -- what is the Ubuntu release you are using? Ubuntu 6.06 (dapper)?

[Andrew Starr-Bochicchio (andrewsomething)]

According to http://packages.ubuntu.com/gutsy/tex/texlive-fonts-recommended

texlive-fonts-recommended includes txfonts, and the source package for texlive-fonts-recommended is texlive-base

Confirmed.

Can be fixed easily. We will se what I can do. In the meantime just do
that:

Hi all,

there is a bug in txfonts.sty, easily reproducible with:
\documentclass{article}
\usepackage{txfonts}
\begin{document}
\verb=\precapprox= prints as \ \ $\precapprox$\\
\verb=\nprecapprox= prints as \ \ $\nprecapprox$\\
\verb=\succapprox= prints as \ \ $\succapprox$\\
\verb=\nsuccapprox= prints as \ \ $\nsuccapprox$
\end{document}

If you compare that with the output using amssymb instead of txfonts you
see that precapprox and succapprox are exchanged. The fix is simple:

--- txfonts.sty.orig 2008-01-22 07:42:45.000000000 +0100

how to fix that bug on CTAN?

Dear Ryu,

I am one of the TeX Live maintainers, upstream and also for Debian. One
user of the Ubuntu packages found a small bug in the txfonts which is
easily seen by trying that:
\documentclass{article}
\usepackage{txfonts}
\begin{document}
\verb=\precapprox= prints as \ \ $\precapprox$\\
\verb=\nprecapprox= prints as \ \ $\nprecapprox$\\
\verb=\succapprox= prints as \ \ $\succapprox$\\
\verb=\nsuccapprox= prints as \ \ $\nsuccapprox$
\end{document}

see that \precapprox and \succapprox are exchanged. The fix is simple:

It would be great if you could fix this (as upstream) and re-upload a
fixed package (only uploading this file should be enough if there are no
other changes) to the CTAN archive, from where it will find its way into
the TeX Live distribution etc.

Thanks a lot for your contribution and all the best

Norbert
