Operation processing
(1) REAL_TO_INT, REAL_TO_INT_E
(a) Converts single-precision real type data input to into word (signed) type data, and
outputs the operation result from .
(b) The value to be input to is single-precision real type data, within the range from
−32768 to 32767.
(c) The converted data is the value rounded single-precision real type data to the first digit
after the decimal point.
