    You could help us, and tell with more details what do you want. Moreover, if you tried anything, the code (even with errors) would be welcome. – Manuel Sep 9 '14 at 11:21

    Just updated a typo in the title (I think) - firs => fits. If that was wrong, sorry. You may also care to reconsider meteorological (=> metrological) in the body. – Brent.Longborough Sep 9 '14 at 15:25
  • Use UTF-8 or maths \plusminus (.0x): ±0.01 – Yiannis Lazarides Sep 9 '14 at 15:56
  • @Brent.Longborough metrology as in an engineering metrology lab, nothing to do with metereology:) – Yiannis Lazarides Sep 9 '14 at 15:59

Perhaps you mean something like this, which I have embodied in the macro

\dscript{upper}{lower}.

Here is my MWE, which uses the layout described at http://www.slideshare.net/Nuumero1/metrology-vtu-unit2-limits-fits-and-tolerances:

\documentclass{article}
\usepackage{stackengine}
\stackMath
\newcommand\dscript[2]{\bgroup\stackon{\scriptstyle#2}{\scriptstyle#1}\egroup}
\setstackgap{S}{1pt}
\begin{document}
$\phi 40^\dscript{+0.05}{-0.05}$
\end{document}

enter image description here

As egreg suggests, and if legibility is not an issue, you may substitute (2 times) \scriptscriptstyle for \scriptstyle in my \dscript definition, in order to obtain the result:

There are other customs for the layout, such as that found at https://books.google.com/books?id=9rNldaV3FwcC&pg=PT372&lpg=PT372&dq=metrology+fits+tolerances&source=bl&ots=E3Bu3oPDQt&sig=RTJmKolkYmg3lEPc6JbfjFJiaI8&hl=en&sa=X&ei=Ox6tVPy4NourggS23oCgBw&ved=0CD0Q6AEwBQ#v=onepage&q=metrology%20fits%20tolerances&f=false , which can be obtained with

\documentclass{article}
\newcommand\dscript[2]{\bgroup#1\egroup_\bgroup#2\egroup}
\begin{document}
$\phi 40^\dscript{+0.05}{-0.05}$
\end{document}

    \scriptscriptsize would be better, in my opinion. – egreg Jan 7 '15 at 8:25
  • Even with the \scriptscriptsize, this implementation seriously disturbs interline spacing. I am not sure if there is a better way. – Paul Gessler Jan 7 '15 at 14:25
  • @PaulGessler These notations tend to be on schematic diagrams, rather than as part of inline text – Steven B. Segletes Jan 7 '15 at 14:57
