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.
→ For the floating point operation, refer to Chapter 18.
Program examples
1. 16-bit operation
