• Multiplies the 32-bit floating decimal point real number designated by (S1) by the 32-bit floating decimal point real number
designated by (S2) and stores the operation result at the device designated by (D).

• Values which can be designated at (S1), (S2) and (D) and which can be stored, are as follows:
-126
| Designated value (stored value) | < 2
0, 2
• When an input value is set using a programming tool, a rounding error may occur. For precautions, refer to Page 89
Precautions.
