javax.sql.rowset.serial.SQLInputImpl.readFloat()
Retrieves the next attribute in this SQLInputImpl object as a float in the Java programming language.
This method does not perform type-safe checking to determine if the returned type is the expected type; this responsibility is delegated to the UDT mapping as defined by a SQLData implementation.
@return the next attribute in this SQLInputImpl object;if the value is SQL NULL, return null @throws SQLException if the read position is located at an invalidposition or if there are no more values in the stream
