Big integers are special beasts that have to be treated
differently than "normal" integers because they can have
an arbitrary size in memory and require a specific handling
not foreseen in "normal" processors.

However big integers are doable and available in every Ada version;
on the following site you'll find a bunch of downloadble packages:

BTW, the freshest version of my multi-precision integers are
in mathpaqs.zip on my Ada page below.
