Operation processing
• These functions convert the BCD type data input to (s) to INT type data and output from (d).
• A value input to (s) is the WORD type data value and within the range from 0H to 9999H (from 0 to 9 for each digit).
■ 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.
