15.45 Converting STRING to INT
STRING_TO_INT(_E)
These functions convert STRING type data to INT type data.
â– Descriptions, types, and data types
â– Operation processing
• These functions convert the STRING type data input to (s) to INT type data and output from (d).
• A value input to (s) is the STRING type data value and within the following range.
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.
