This package is unneeded and does nothing when used with a LaTeX format 2020-10-01 or newer as in this case the format provides the \AtEndDvi command. For older formats it implements \AtEndDvi, a counterpart to \AtBeginDvi. The execution of its argument is delayed to the end of the document at the end of the last page. Thus \special and \write remain effective, because they are put into the last page. This is the main difference to \AtEndDocument.

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 specifying 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 $26\times10\,^{6}$.
