ED/
 Divides the 64-bit floating-point real number designated by (S1) by the 64-bit floating-point real number designated by (S2)
and stores the result of the division at the device designated by (D).
S1+3 S1+2 S1+1 S1
64-bit floating-point real
number
 The following values can be designated and stored by (S1), (S2), or (D).
-1022
0, 2 ≤ | Designated value (stored value) | < 2
 When the operation results in "-0" or an underflow, the result is processed as "0".
 When setting input values from programming tools, rounding errors may occur.
For precautions when setting input values from programming tools, refer to "6.3.4 Single/Double-Precision Real Number
Data".
 Operation errors
 In the following cases, an arithmetic error occurs, the error flag (SM0) turns ON, and an error code is stored at SD0.
- The divisor (S2) is "0". (Error code: 34)
- The operation result exceeds the following range. (When an overflow occurs) (Error code: 36)
| Operation result | < 2
- The designated device value is not within the following range. (Error code: 35)
-1022
0, 2 ≤ | Designated device value | < 2
- The designated device value is "-0", unnormalized number, nonnumeric, or ± ∞ . (Error code: 35)
