xlop is still under construction.  In fact, xlop 0.2 is just a beta
release; xlop 0.3 will provide:

  * Full redefinition about internal number representation (faster
    and less memory space).
  * Some macros improved (\opprint, \opdisplay, \opput, ...).
  * New parameters (format=normal/sci/eng, carrymul,
    hyphen (multiline for very long numbers), fine division and
    multiplication control, ...)
  * Calculation on basis 2 to 36
    e.g. \opadd[style=text]{"2"11010}{"2"10010} will display
        11010 + 10010 = 101100
  * Support language (languages defined in babel, oldrussian, and
    babylon) e.g. \div[displayintermediary=all]{33}{2} displays
