Announcement text given by the package's contributor:
The siunitx package --- A comprehensive (SI) units package
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). A number of LaTeX packages have been developed to provide consistent application of the various rules: SIunits, sistyle, unitsdef and units are the leading examples. The numprint package provides a large number of number-related functions, while dcolumn and rccol provide tools for typesetting tabular numbers.
The siunitx package takes the best from the existing packages, and adds new features and a consistent interface. A number of new ideas have been incorporated, to fill gaps in the existing provision. The package also provides backward-compatibility with SIunits, sistyle, unitsdef and units. The aim is to have one package to handle all of the possible unit-related needs of LaTeX users.
This release is the second public version of the package, which was originally released as si in February 2008. Thanks to all of the feedback contributors to date, many of whom have provided valuable ideas for this new release. The new version brings with a a large number of changes (see siunitx.pdf for a full list). Many of these are internal, and so the headline changes only are given here.
Major/interface changes:
- Package name change from si to siunitx, to make searching
archives easier and to emphasise unit-related nature of the package.
- unitsym macro renamed si
- Now use e-TeX protected mechanism for all user macros and
units
- unitsdef-like unit macros can now be turned on and off,
allowing direct use of single unit macros in running text
- Various improvements to handling of numerical input, such
as removal of excess leading zeros
- Potential macro names clashes with other packages handled
better; known clashing macros all available with doubled initial letter (e.g. ssquare, bar, ...)
- meter added to package kernel
- liter defined along with litre
Bug fixes:
- Material added to columns by array package
({stuff}>c<{more stuff}) now works correctly when s column is last in a table
- Errors in some unit definitions fixed
- Fixed minor alignment bug in tabular material
- Binary units now give correct base when using
prefixsymbolic=false option
Option changes:
- Separated out font macros into unit and value variants
- Tabular options overhauled: tabalign, tabtextalign,
tabformat now used for fine control
- Several options given clearer names
- New options added to support new features
New features:
- Colour support
- fancynum and fancyunits emulation
- Better control of alignment of tabular material
- Automated handling of error data in numbers
- per macro can now be set to sticky
Plus a large amount of work on documentation, including much better description of package options. The package documentation needs quite a complete TeX system to compile. It is therefore provided pre-built in two versions: - siunitx.pdf includes code - 158 pages - siunitx-manual.pdf
- user documentation only, 43 pages The later should be
okay for most users.
Feedback on all aspects of the package is welcome. The current road map allows one more release with arbitrary interface changes. Comments on macro and option names are therefore particularly welcome at this stage.
Please be advised that this package is in beta stage and released for testing only. TeX distributors are advised to wait for version 1.0. The version number will be stepped up to 1.0 as soon as it is considered suitable for general distribution.
