Decimals of the average value are rounded off so that the average value is an integer.
Precaution during programming
Even if D + 5 overflows the selected area, it will still be stored, and this may corrupt the data in the leading part
of the other area. (An area overflow check is not performed.)
Flag conditions
・Error flag (R9007): Turns on and stays on when:
・Error flag (R9008): Turns on for an instant when:
− The area specified using the index modifier exceeds the limit.
− S1 > S2.
− The areas of S1 and S2 are different.
・Carry flag (R9009): Turns on for an instant when overflows/underflows while calculating.
