Example:
When B010 is ON, the double-word data of D0101×D0100 is compared with the double-word
data of D0251×D0250, and if the data of D0101×D0100 is greater than or equal to the data of
D0251×D0250, B014 is turned ON.
If the data of D0101×D0100 is 250000 and D0251×D0250 is 200000, B014 is turned ON.
If the data of D0101xD100 is -100 and that of D0251xD0250 is 0, the comparison result is false.
Consequently, B014 is turned OFF.
