*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.
Operation error
• When (s1) to (s28) are of REAL data type
• When (s1) to (s28) are of LREAL data type
Execution condition Operation result
