Outline of operation
● According to the operation unit [i], the single-precision floating point real number value, which
is stored in the area starting with [S], is converted to an integer value (rounding the first
decimal point down).
● The calculation result is stored in the area starting with [D].
● The data setting ranges for conversion target data [S] by operation units are indicated below.
