Operation Error
(1) In any of the following cases, an operation error occurs, the error flag (SM0) turns ON, and
an error code is stored into SD0.

Program Example
(1) The following program converts the 32-bit floating decimal point type real number at D20
and D21 to BIN 16-bit data, and stores the result at D0.
