Processing details
• These instructions convert the single-precision real number in the device specified by (s) to 16-bit signed binary data, and
store the converted data in the device specified by (d).
• After conversion, the first digit after the decimal point of the single-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.
