(2) The values that can be designated by , , and are in the range of from 32768 to
32767.
(3) The output value stored at is a signed 16-bit BIN value. Therefore, if the operation results
exceed the range of 32768 to 32767, the following will take place:
Output value 32768 + ( 100) 8000

DZONE
(1) Adds bias value designated by ( , +1) or ( , +1) to input value designated by ( ,
+1), and stores the result at device number designated by ( , +1).
Addition of the bias value is performed as follows:
(2) The values designated by ( , +1), ( , +1), or ( , +1) are within the range of from
2147483648 to 2147483647.
(3) The value stored at ( , +1) is a signed 32-bit BIN value.
Therefore, if the operation results exceed the range of from 2147483648 to 2147483647,
the following takes place:
Output value 2147483648 + ( 1000) 80000000
