siunitx - A comprehensive (SI) units package
|
||
|
|
==============================================
|
||
|
|
|
||
|
|
Physical quantities have both numbers and units, and each
|
||
|
|
physical quantity should be expressed as the product of a number
|
||
|
|
and a unit. Typesetting physical quantities requires care to
|
||
|
|
ensure that the combined mathematical meaning of the number-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
|
||
|
|
quantities 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 . 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
|
||
|
|
`l3kernel` and `l3packages` bundles. Both of these are available
|
||
|
|
on [CTAN](http://www.ctan.org/) as ready-to-install zip files.
|
||
|
|
Suitable versions are available in MiKTeX 2.9 and TeX Live 2012
|
||
|
|
(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`
|
||
|
|
- `cancel`
|
||
|
|
- `caption`
|
||
|
|
- `cleveref`
|
||
|
|
- `colortbl`
|
||
|
|
- `csquotes`
|
||
|
|
- `datatool`
|
||
|
|
- `helvet`
|
||
|
|
- `mathpazo`
|
||
|
|
- `multirow`
|
||
|
|
- `listings`
|
||
|
|
- `pgfplots`
|
||
|
|
- `xcolor`
|
