8.9 Real Number Instruction
Multiplying single-precision real numbers
E*(P)
These instructions multiply the single-precision real number in the device specified by (s2) to the single-precision real number
in the device specified by (s1), and store the result in the device specified by (d).
*1 Supported by engineering tool version "1.035M" and later.

Processing details
• These instructions multiply the single-precision real number in the device specified by (s2) to the single-precision real
number in the device specified by (s1), and store the result in the device specified by (d).
• Values in the devices specified (stored) by (s1), (s2), and (d) should be 0 or 2
