Operands
| Operand | Description |
|---|---|
| S1 | The first operand. Entries are REAL data registers or constants. This is the dividend. The value range is 2-127 ~ 2128 (-1.7014118e+38 ~ 3.4028237e+38). |
| S2 | The second operand. Entries are REAL data registers or constants. This is the divisor. The value range is 2-127 ~ 2128 (-1.7014118e+38 ~ 3.4028237e+38). |
| D | The third operand. Entries are only REAL data registers. This is where the product is saved. |

Notice
Error Flag (F11.0) Notice
The error flag, F11.0, will be ON for one scan when the address of the data register assigned by @D exceeds the range of the data register, D. The range of the data register, D, is dependent on the CPU type.
F11.0 turns ON when the value of the data for dividing exceeds the data register assigned to S1 or S2.
F11.0 turns ON when the value of the divisor, S2, is 0.
Tip: Operand Division Format
S1 is divided by S2.
(S1 ÷ S2)
