15.35 Converting REAL to INT
REAL_TO_INT(_E)
These functions convert REAL type data to INT type data.
â– Descriptions, types, and data types
â– Operation processing
• These functions convert the REAL type data input to (s) to INT type data and output from (d).
• A value input to (s) is the REAL type data value and within the range from -32768 to 32767.
• After conversion, the first digit after the decimal point of the REAL type data value is rounded off.
â– 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.
