Seems to be fixed in OTP 24 now:

OTP-17077    Application(s): compiler, erts, stdlib
               Related Id(s): ERL-1431, PR-2903, PR-2905, PR-2906

               A floating point zero (0.0) can be both positive (+0.0)
               and negative (-0.0). Multiple bugs in the compiler,
               runtime system, and STDLIB have been fixed to ensure
               that the minus sign on 0.0 is not lost.
