MOD
The MOD instruction finds the remainder for division of integers.
* If you omit an input parameter, the default value is not applied. A building error will occur.
The MOD instruction divides dividend In1 by divisor In2 to find the remainder. The data types of In1,
In2, and remainder Out can have different data types.
This instruction performs the calculation with the following formula.
Out = In1 − (In1/In2)* In2 (The decimal point is truncated in the division operation.)
Examples of the values of In1, In2, and Out are given in the following table.
