And current mathematician have them with infinitesimally small numbers ;)
Not really. Everyone agrees that calculus can be done with infinitesimals, but most mathematicians think that doing it with limits forms a better basis for going on to real analysis and epsilon-delta proofs later.
I don’t think modern mathematicians are going to drown someone for using infinitesimally small numbers...
Non-standard analysis is perfectly fine. Most mathematicians just don’t deal with that kind of analysis.
