Hi internals, I have reflected the discussion up to this point in the RFC. https://wiki.php.net/rfc/support_object_type_in_bcmath
However, the point that the argument of `round()` is "precision" has not yet been reflected in the RFC. The argument names of standard's `round()` are also the same, and we are currently discussing this point in the implementation PR of `bcround()`. Regards, Saki
