---------------------------------------------------------------- The siunitx package --- A comprehensive (SI) units package Maintained by Joseph Wright E-mail: joseph.wright@morningstar2.co.uk Released under the LaTeX Project Public License v1.3c or later See http://www.latex-project.org/lppl.txt ---------------------------------------------------------------- Typesetting values with units requires care to ensure that the combined mathematical meaning of the value plus unit combination is clear. In particular, the SI units system lays down a consistent set of units with rules on how these are to be used. However, different countries and publishers have differing conventions on the exact appearance of numbers (and units). The siunitx package provides a set of tools for authors to typeset numbers and units in a consistent way. The package has an extended set of configuration options which make it possible to follow varying typographic conventions with the same input syntax. The package includes automated processing of numbers and units, and the ability to control tabular alignment of numbers. Installation ------------ The package is supplied in dtx format and as a pre-extracted zip file, siunitx.tds.zip. The later is most convenient for most users: simply unzip this in your local texmf directory and run texhash to update the database of file locations. If you want to unpack the dtx yourself, running 'tex siunitx.dtx' will extract the package whereas 'latex siunitx.dtx will extract it and also typeset the documentation. The package requires LaTeX3 support as provided in the expl3 and xpackages bundles. Both of these are available on CTAN (http://www.ctan.org/) as ready-to-install zip files. Suitable versions are available in MiKTeX 2.8 and TeX Live 2010 (updating the relevant packages online may be necessary). LaTeX3, and so siunitx, requires the e-TeX extensions: these are available on all modern TeX systems. Typesetting the documentation requires a number of packages in addition to those needed to use the package. This is mainly because of the number of demonstration items included in the text. To compile the documentation without error, you will need the packages: - amsmath - booktabs - caption - cleveref - csquotes - datatool - helvet - mathpazo - listings - pgfplots - xcolor The xfrac package is also loaded if available, but is not required to typeset the documentation.
