I was wondering what's the best programming language (and development community) for integer mathematics?
I'm an R supporter. However, I'm interested in primality testing and integer factorization, including large integers. And I'm not sure that R (and CRAN) is the best option.
Any suggestions?
Python has had large-integer support for many years.
Also, the "Sage" mathematics environment includes many, many pre-computed things, and is based on Python.
Both are open-source, etc. Easy choice, if one has even the faintest desire to be open-source.
