The last topics appeared to be my partial questions on something more general... From my research and extensive help from other users (like Bernard) I managed to use newtxmath and newtxtext packages in formatting of my simple document.

I would also like to use the \pi as presented here:

Formatting of \pi

Bernard pointed out that such \pi is from the TeX Gyre Termes family:

http://texdoc.net/texmf-dist/doc/fonts/tex-gyre/qtm-info.pdf

However, I am completely unable to use it. My current (very simple test) document preamble looks like this:

\documentclass[a4paper,12pt]{article}
\usepackage{tgtermes}
\usepackage{newtxtext}
\usepackage{newtxmath}
\pagestyle{empty}
\begin{document}
This is text: $\int$ $y$, $\pi$.
\[\int y \pi\]
\end{document}

But this does not provide the fonts presented in the linked PDF above (namely \pi symbol).

I try to use MiKTeX 2.9 with Led editor. Many thanks for helping.

You don't need to load tgtermes separately, I don't think, as newtxtext uses those fonts anyway. But you do need to tell newtxmath that you want upright Greek:

\documentclass[a4paper,12pt]{article}
\usepackage{newtxtext}
\usepackage[uprightGreek]{newtxmath}
\pagestyle{empty}
\begin{document}
  This is text: $\int$ $y$, $\pi$.
  \[\int y \pi\]
\end{document}

upright Greek

With frenchmath you get upright Greek but also some other things you might not wish:

\documentclass[a4paper,12pt]{article}
\usepackage{newtxtext}
\usepackage[frenchmath]{newtxmath}
\pagestyle{empty}
\begin{document}
  This is text: $\int$ $y$, $\pi$.
  \[\int y \pi\]
\end{document}

frenchmath

With no options, you can still access the upright pi using \piup:

2 pi

Or you can make just this the default i.e. just affect this symbol using \let\pi\piup:

\documentclass[a4paper,12pt]{article}
\usepackage{newtxtext}
\usepackage{newtxmath}
\pagestyle{empty}
\let\pi\piup
\begin{document}
  This is text: $\int$ $y$, $\pi$.
  \[\int y \pi \piup\]
\end{document}

pi pi pi

  • I tried but the result is identical when using or not using the [uprightGreek]. Also the code is not from the original TeX Gyre Termes family. – rk85 Jun 4 '15 at 16:09
  • @Radek Do you want just the pi upright? Or all the Greek? For some reason, the package only uses upright Greek generally with the French maths spacing option... Otherwise, you get some upright Greek, but it is a limited set. You can use \piup for upright pi. Do you want just to access it or have it be what you get with \pi? – cfr Jun 4 '15 at 16:32
  • @Radek See edits for some possibilities. – cfr Jun 4 '15 at 16:37
  • I would like to use all the symbols exactly like in texdoc.net/texmf-dist/doc/fonts/tex-gyre/qtm-info.pdf. For example pi has been identified by user Bernard as 03C0 (page 10), but I'm completely unable to use these fonts and formatting style. – rk85 Jun 4 '15 at 16:38
  • @Radek Sorry, but that doesn't make sense. There are, for example, 4 pi symbols for that point in unicode. \pi will produce one of them, at least within any given context. You can have it produce the upright one or the italic one by default. I don't understand why you say you can't use the fonts or the style. Your MWE uses the fonts. And my answer shows how to access the upright pi in various ways. (The edited version, that is.) – cfr Jun 4 '15 at 16:41

Note that the TeX Gyre Termes math fonts, which are OpenType, are only available for Xe(La)TeX or Lua(La)TeX (yet?). You have to switch to one of these engines if you want to use them.

\documentclass[12pt]{article}
\usepackage{unicode-math}
\setmainfont{TeX Gyre Termes}
\setmathfont{TeX Gyre Termes Math}
\begin{document}
The $\pi$ number.
\end{document}

enter image description here

  • I see. Any tips / procedures how to proceed with such switch using MiXTeX and Led? – rk85 Jun 4 '15 at 16:48
  • @Radek I know very little of Windows and I never used MikTeX nor Led, so I can't be of any help for this… – Franck Pastor Jun 4 '15 at 17:02
  • OK. Managed to transfer to XeLaTeX:) But now I have some problems with using newtxtext and newtxmath in text and equations, but these TeX Gyre Termes fonts for greek letters. The I specify \usepackage{unicode-math} \setmainfont{TeX Gyre Termes} \setmathfont{TeX Gyre Termes Math} math font change considerably. – rk85 Jun 4 '15 at 19:15
  • @Radek The newtx math fonts are type 1 (PostScript) and have not the same design as the TeX Gyre Termes math fonts. It is not recommended to mix them. You should make a choice between both… – Franck Pastor Jun 4 '15 at 20:06
  • Though I bet it is possible to make such mix:) I would in general like to use newtx math but with some selected symbols from TeX Gyre Termes. – rk85 Jun 5 '15 at 8:39
