27 ARITHMETIC OPERATION FUNCTIONS
27.4 Division
27.4
Division
DIV(_E)
These functions output the quotient of input values ((s1)

(s2)).

Processing details
■ Operation processing
• These functions perform division between the INT, DINT, REAL, or LREAL data type values input to (s1) and (s2)
((s1)

(s2)), and output the operation result, in the same data type as (s), from (d).
Ex.
Data type: INT
• Input an INT, DINT, REAL, or LREAL data type value to (s1) and (s2). provided that the value input to (s2) shall be other
than 0.
■
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.
