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
• When an input value is set from the engineering tool, a rounding error may occur.
