SHORT DESCRIPTION
=================

(This is a copy of the LaTeX code of the documentation's abstract.)

\textsf{ionumbers} stands for `input/output numbers'.

This package restyles numbers in math mode. If a number in the input file
is written, e.g., as |$3,231.44$| as commonly used in English texts, this
package is able to restyle it to be output as `$3\,231{,}44$' as commonly
used in German texts (and vice versa). This may be very useful, if you have
a large table and want to include it in texts with different output
conventions without the need of changing the table.

Furthermore this package can automatically group digits left to the decimal
separator (\emph{thousands}) and right to the decimal separator
(\emph{thousandths}) in triplets without the need of specifing commas
(English) or points (German) as separators. E.g., the input |$1234.567890$|
can be output as `$1\,234.\,567\,890$'.

Finally, an |e| starts the exponent of the number. For example, |$21e6$|
may be output as `$26\times10\,^{6}$'.

See `ionumbers.pdf' for detailed information on usage.

BUILDING
========

If you do not want to use any pre-build `ionumber.sty' and `ionumber.pdf'
files, you will have to choose one of the following two ways for building them.
Otherwise you can skip this section.

1) Building with make
---------------------

Running `make' will create the LaTeX package, the documentation and the test
file:
  $ make

2) Building manually
--------------------

a) Generation of package (.sty file):

Run `ionumbers.ins' through LaTeX:
  $ pdflatex -interaction=nonstopmode ionumbers.ins

b) Generation of documentation:

Run `ionumbers.dtx' through LaTeX:
  $ pdflatex -interaction=nonstopmode ionumbers.dtx

Then create the index and change history:
  $ makeindex -s gind.ist -o ionumbers.ind ionumbers.idx
  $ makeindex -s gglo.ist -o ionumbers.gls ionumbers.glo

Finally, run `ionumbers.dtx' three time through LaTeX:
  $ pdflatex -interaction=nonstopmode ionumbers.dtx
  $ pdflatex -interaction=nonstopmode ionumbers.dtx
  $ pdflatex -interaction=nonstopmode ionumbers.dtx

Optionally you can compile the test file:
  $ pdflatex -interaction=nonstopmode ionumbers_test.tex
  $ pdflatex -interaction=nonstopmode ionumbers_text.tex
  $ pdflatex -interaction=nonstopmode ionumbers_text.tex

INSTALLATION
============

Copy the file `ionumbers.sty' to a directory, where LaTeX will find it.
