Name of contribution: ionumbers Author's name: Christian Schneider Location on CTAN: /macros/latex/contrib/ionumbers Summary description: restyle numbers in math mode License type: gpl
Announcement text: ---------------------------------------------------------------------- `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 (thousands) and right to the decimal separator (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 `$26 imes10,^{6}$'. ----------------------------------------------------------------------
