Error
1) An operation error occurs when the divisor stored in a device specified in is "0", and the function is
not executed.
2) An operation error occurs when the operation result exceeds "32,767" (16-bit operation) or
"2,147,483,647" (32-bit operation).
Program example
In this program, division is performed using double word [signed] data stored in devices specified in and
, and the remainder is output to a device specified in using the data type of data stored in devices
specified in and .
1) Function without EN/ENO(MOD)
2) Function with EN/ENO(MOD_E)
