Cautions
1. Devices specified in
• In a 32-bit operation (by DMUL or DMULP), Z cannot be specified in
2. When monitoring the operation result in a programming tool
Even if word devices are used, the operation result (64 bits) cannot be monitored at one time.
In such a case, floating point operation is recommended.
Program examples
