I'm quite sure that would be a grossly inefficient approach. Sending a message is expensive in Erlang, less so than in other languages, but it's still very large compared to a few math operations. It's a common mistake to use processes to represent objects [1].
The recent article from Discord [2] also mentioned "Sending messages between Erlang processes was not as cheap as we expected, and the reduction cost — Erlang unit of work used for process scheduling — was also quite high. We found that the wall clock time of a single send/2 call could range from 30μs to 70us due to Erlang de-scheduling the calling process."
