Processing details
• These instructions convert the double-precision real number in the device specified by (s) to 16-bit unsigned binary data,
and store the converted data in the device specified by (d).
• After conversion, the first digit after the decimal point of the double-precision real number is rounded off.
• When an input value is set using the engineering tool, a rounding error may occur. For the precautions on setting an input
value using the engineering tool, refer to the following.
