Basic package information, as sent by the contributor. ------------------------------------------------------------------------ Location: /macros/latex/contrib/siunitx Caption: A comprehensive (SI) units package. Description: 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 they 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.
The package relies on LaTeX 3 support from the expl3 and xpackages bundles. Author: Joseph Wright License: lppl1.3 Name: siunitx Version: 2.0w ------------------------------------------------------------------------
