siunitx, how to include Greek letters in number field of \SI ?
Zarko F. Cucej
is there a (simple) way to express a magnetic constant μ_0 = 4π×10^{−7}
by siunitx? Something like \SI{$4\pi$e-7}{H/A} (which make an error ...)
Actually, in some my texts (exercises) I intensively use normalized
frequencies like $0,25\pi$ rad/s or \pi/8 s^{-1} etc, so I will be very
happy if I can write math expression in \SI (which now allows only pure
numbers) or in special defined environment (like \unit in SIunit package)
regards, Zarko

See for example p.42 of the current (v1.2) manual
\documentclass{article}
\usepackage{siunitx}
\begin{document}
\num[numaddn=\pi]{4\pi e-7}
\SI[numaddn=\pi]{4\pi e-7}{\henry\per\ampere}
\end{document}
(You may need to watch your fonts here: it is a bit awkward to cover
every circumstance.)

Draer Joseph Wright,
thank you very much for your answer. I will test above possibilities it
when Miktex will include last version of siunitx package (I don't prefer
manual upgrading of particular packages in MikTeX).

This should work fine in every release version of siunitx. It's just
that the page in the manual varies from release to release!

Well, i didn't find this option in old manual, so I think that this
possibility is new in latest version of siunitx ...
and indeed, there is mess with characters or with encoding. Instead of
\pi it appear as German character for ss. I use the following fonts and
encodings:
\usepackage[T1]{fontenc}\usepackage[cp1250]{inputenc}
\usepackage[slovene]{babel}
\usepackage{palatino,mathpazo,marvosym,pifont}
\usepackage[scaled=0.88]{helvet}
what to do?

This is a known issue, and I'm a bit limited on what I can do "out of
the box", as there are issues with different combinations of mode,
fonts, etc. For your case, I'd do:
\documentclass{article}
\usepackage[T1]{fontenc}
\usepackage[cp1250]{inputenc}
\usepackage[slovene]{babel}
\usepackage{mathpazo,marvosym,pifont} % mathpazo covers palatino
\usepackage[scaled=0.88]{helvet}
\usepackage{siunitx}
\protected\def\SIpi{\mathnormal\pi}
\sisetup{numaddn=\SIpi}
\begin{document}
\num{4\SIpi e-7}
\SI{4\SIpi e-7}{\henry\per\ampere}
% Or redefine \pi
\let\SIpi\pi
\protected\def\pi{\mathnormal\SIpi}
\sisetup{numaddn=\pi}
\num{4\pi e-7}
\SI{4\pi e-7}{\henry\per\ampere}
$\pi r^2$
\end{document}

Thank you very much!
Above option work fine, but with second one I receive error: \pi already
defined. Maybe I miss something, so I will give another try after more
carefully reading of documentation for siunitx!

Should be nothing to do with siunitx (I hope). Did you use my example
exactly? What does \listfiles say? I get:

Sorry for latte response. my internet provider has some difficulties
with his news server ...
I found a cause of error: \pi already define. It was order of definition
and packages. I have siunitx and definition of \pi before of package
mathpazo. When I put the mathpazo on the top, error disappear.
Thank you very much for your help and great package!
