    The  rounding  is of course correct. Rounding 0.1234567 first
    to 0.123457 and then cutting of to 0.1234 is finally cutting,
    not rounding, and totally braindead. You only have to look at
    the digit after the last significant one.  In  this  case  we
    have  4  significant  digits,  so  we  must  look at digit 5,
    nothing else. Thus 0.1234500 is  0.1235  while  0.1234499  is
    0.1234 - end of story.

    The  other  one,  not  beeing able to insert 0.0, is surely a
    bug. Would you please put it onto the TODO?
