My overriding concern at this time is to allow (or not) the operations consistently (that is, not making it platform-specific). The net result is that we will allow operations between the two types; however, we will encounter a further issue to discuss on what the common type should be when the representations are the same (the TS prefers `long double`).

As for the diagnostics, the `__float128
