Operation processing
• These functions convert the REAL type data input to (s) to DINT type data and output from (d).
• A value input to (s) is the REAL type data value and within the range from -2147483648 to 2147483647.
• After conversion, the first digit after the decimal point of the REAL type data value is rounded off.

Operation result
1.
Function without EN/ENO
The following table lists the operation results.
2.
Function with EN/ENO
The following table lists the execution conditions and operation results.
*1 When FALSE is output from ENO, data output from (d) is undefined. In that case, modify a program so that the data output from (d) is
not used.
