Modulo
Returns the remainder of dividing one whole number by another.
Modulo divides the first whole number by the second and gives you what is left over. Use it to find even and odd numbers (remainder of dividing by 2), to act on every N-th item in a loop, or to spread items across a fixed number of groups.
Add the action
In the Process Designer toolbox, open Numerical and pick Modulo (or type Modulo in the search box).
Inputs and outputs
| Field | Direction | Type | Required | What to put / what you get |
|---|---|---|---|---|
| First number | Input | Integer | Yes | The number to divide. |
| Second number | Input | Integer | Yes | The number to divide by. Cannot be 0. |
| Result | Output | Integer | Yes | The remainder. |
Example
| First number | Second number | Result |
|---|---|---|
17 | 5 | 2 |
-17 | 5 | -2 |
17 | -5 | 2 |
17 | 0 | step fails: Divisor cannot be 0. |
Good to know
- Whole numbers only. A decimal such as
17.5stops the step with an error. - The remainder takes the sign of the first number:
-17modulo5is-2, not3. If you need a result that is never negative, add the second number to a negative result. - A number is even when Result is
0for a Second number of2.
