<str> is being converted from NUMBER to <str>

  Explanation:  The NUMBER format is supported by Rdb by being
  converted to another underlying data type.  Support includes
  limiting the precision limits (values 1 through 18 only).
  NUMBER without precision and scale, or with precision greatre
  than 18 will default to DOUBLE PRECISON.
