no_trailing_dot_policy rejects parsing exp, exp_n, nan, inf and rejects parsing a fractional part if detects ".Fmt". For Fmt = 'j', 's', 'o', 'n': 42.foo rule parses 42. 42.json rule parses 42 42..json rule parses 42. Reference: - https://github.com/Project-OSRM/osrm-backend/pull/2222#issuecomment-206206239
