25 TYPE CONVERSION FUNCTIONS
25.56 Converting STRING to INT
25.56 Converting STRING to INT
STRING_TO_INT(_E)
These functions convert a value from STRING data type to INT data type.
Setting data
■Description, type, data type
Processing details
■Operation processing
• These functions convert the value input to (s) from STRING data type to INT data type, and output the converted value from
(d).
• Input a STRING data type value to (s) within the following range.
■Operation result
1. Function without EN/ENO
The operation processing is performed. The operation result is output from (d).
2. Function with EN/ENO
The execution conditions and operation results will be as follows.
*1 If the value FALSE is output from ENO, the output data from (d) will be undefined. Create a program so that the undefined value will not
be used in operations.
