Надыбал в коде такой алгоритм округления, круто Laughing

Code:
* correct rounding errors
    CASE l_difference.
      WHEN '0.01'.
        CASE l_current_per.
          WHEN '06'.
            l_correct = ' - 0.01'.
        ENDCASE.
      WHEN '0.01-'.
        CASE l_current_per.
          WHEN '07'.
            l_correct = '0.01'.
        ENDCASE.
      WHEN '0.02'.
        CASE l_current_per.
          WHEN '03' OR '09'.
            l_correct = '- 0.01'.
        ENDCASE.
      WHEN '0.02-'.
        CASE l_current_per.
          WHEN '04' OR '10'.
            l_correct = '0.01'.
        ENDCASE.
      WHEN '0.03'.
        CASE l_current_per.
          WHEN '02' OR '06' OR '10'.
            l_correct = '- 0.01'.
        ENDCASE.
      WHEN '0.03-'.
        CASE l_current_per.
          WHEN '03' OR '07' OR '11'.
            l_correct = '0.01'.
        ENDCASE.
      WHEN '0.04' OR '0.04-'.
        CASE l_current_per.
          WHEN '02' OR '05' OR '08' OR '11'.
            IF l_difference < 0.
              l_correct = '0.01'.
            ELSE.
              l_correct = '- 0.01'.
            ENDIF.
        ENDCASE.
      WHEN '0.05'.
        CASE l_current_per.
          WHEN '02' OR '04' OR '06' OR '09' OR '11'.
            l_correct = '- 0.01'.
        ENDCASE.
      WHEN '0.05-'.
        CASE l_current_per.
          WHEN '02' OR '04' OR '07' OR '09' OR '11'.
            l_correct = '0.01'.
        ENDCASE.
      WHEN '0.06' OR '0.06-'.
        CASE l_current_per.
          WHEN '02' OR '04' OR '06' OR '08' OR '10' OR '12'.
            IF l_difference < 0.
              l_correct = '0.01'.
            ELSE.
              l_correct = '- 0.01'.
            ENDIF.
        ENDCASE.
      WHEN OTHERS.
        l_correct = 0.
    ENDCASE.
