    Use to_number function.
    E.g.
    SQL> select to_number('234E5') from dual;

    TO_NUMBER('234E5')

    If this is merely a display issue, could you select:

    to_char(YourNumField,'99999999999999999999999999999999999999') from dual;

    ?
    Then if you need to do math, convert it back. The math still works correctly.

    The format model for scientific notation is 'EEEE', that is 4 letters "E".

    SQL> set numwidth 12
    SQL> select to_number('5.20626E+11','9.99999EEEE') from dual;

    TO_NUMBER('5.20626E+11','9.99999EEEE')
    --------------------------------------
