Answer 1

Python and Java have native support, libraries exist for C++, C, .NET, ...

Answer 2

I know that Erlang has support for unlimited size int arithmetics.

Answer 5

Perl, Python, Ruby, and Java can all do that. External libraries exist for everything else.

I rather like Ruby and Python because they automatically switch from Fixnum to Bignum. (Python: int to long.)

Answer 6

In C or C++, you can use GMP (Gnu Multi-Precision library).

In Perl, you can use the bignum module.
