Hi

About Approximate operator, you can go to tcode 'ABAPDOCU', searching CO,CN,CA etc...each of them have example there.

And recursive function,

Say here is a FM,

FUNCTION recursive_get_number.

*import im_num type i.

*export ex_num type i.

ex_num = im_num + 1.

IF ex_num GE 100.

   EXIT.

ELSE.

   CALL FUNCTION recursive_get_number

        EXPORTING

           im_num = ex_num

        IMPORTING

           ex_num = ex_num.

ENDIF.

ENDFUNCTION.

When you call this function from outside with importing parameter '1',  then will return you 100.

Archer.
