Ran into the same limitation with excbor.  I used tuples to represent them, to keep the three values related:

  def decode_non_finite(0, 0), do: {CBOR.Tag, :float, :inf}
  def decode_non_finite(1, 0), do: {CBOR.Tag, :float, :"-inf"}
  def decode_non_finite(_, _), do: {CBOR.Tag, :float, :nan}

(where the two parameters are the sign and the mantissa).
