Processing details
• These instructions convert the single-precision real number in the device specified by (s) to 32-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 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.
The following program example converts, when M0 turns on, the single-precision real number stored in D0 and D1 to 32-bit
unsigned binary data, and stores the converted data in D100 and D101.
