still something fishy with the 3rd problem, example: x = uint64(321676750829977632); num2str(x) -> 321676750829977600 rem(x,10) -> 0 euler003(x) -> 83653987 ...?

ok now, it seems this was only an issue with my matlab version (7.7) but was not present in the version running the solvers (which seems to have uint64 arithmetic supported!, man, I need an upgrade...)
