 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 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)
- The operation result exceeds the following range. (When an overflow occurs) (Error code: 36)
| Operation result | < 2
 Program example
 The following program converts the radian value set as a 64-bit floating-point real number from D20 to D23 to an angle, and
stores the result at D30 as a BCD value.
