Yes.  cbor.me currently only offers what I hope will be the Common CBOR Deterministic Encoding Profile.  It does not implement the dCBOR application profile, whose job it would have been to turn the floating-point 4 (floating point as indicated by the presence of a decimal point) into an integer 4.  Let’s see when I get to including a dCBOR flag in the cbor.me user interface...
