Metrology tolerance and fits

Question

How can i type meteorological tolerance, limits and fits etc, like double superscripts one on another notations using latex can any one please help me in this regard?

Answer 1

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}

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}
