 Post subject: Suggestion for really large integers in Alglib?

Hello guys,

I'm having the problem of using really large integers, like 1e30 ~ 1e40. I searched and found that boost and gmp could be a great choice:
http://www.boost.org/doc/libs/1_60_0/libs/multiprecision/doc/html/boost_multiprecision/tut/ints/gmp_int.html

The problem is that if I use the data structure in boost to define large integers that form a matrix, how could I use alglib optimization and eigenvalue solvers? Any suggestion for that?

Thanks in advance!

There is an old version of ALGLIB (2.x branch) which supports multiple precision floats, you may try using it.
