Even though I am not a seasoned programmer, I think I'll have to write the tool myself. My question is, will it be reasonably simple to handle large rational numbers with Ada? Is there any packages for this? Does basic Ada (gnat) support (f.ex.) 2048-bit integers? Does any module exist for integers of dynamic size? Are these handled reasonably efficiently, or is there much overhead? I guess I will manage to implement the rational numbers without too much hardship, but I really don't feel like implementing arithmetics on large integers. :-- Hans Georg -- Signature en panne.
