# ionumbers – Restyle numbers in maths mode

‘`ionumbers`’ stands for ‘input/output numbers’.

The package restyles numbers in maths mode. If a number in the
input file is written, e.g., as `$3,231.44$` as commonly
used in English texts, the 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 useful, for example, if you have a
large table and want to include it in texts with different output
conventions without the need to change the table.

The package can also automatically group digits left of the
decimal separator (thousands) and right of 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
`$26\times10\,^{6}$`.
