Outline of operation
● This instruction converts the double-precision floating point real number data stored in the
area starting with [S] to an integer (the largest possible integer without exceeding the real
number).
● The conversion result is stored in the area starting with [D].
●
The data setting ranges for conversion target data [S] by operation units are indicated below.
