## Parameters

These are the parameters you need to configure to use this operation (mandatory parameters are marked with a <mark style="color:red;">**\***</mark>):

<details>

<summary>Delimiter<mark style="color:red;"><strong>*</strong></mark></summary>

Choose the delimiter that separates the numbers in your input data. enter one of the following:

* **Line feed** - Select this to have each line of text as a separate value.
* **Space** - Your numbers are separated by spaces.
* **Comma** - Your numbers are separated by commas (`,`)
* **Semi-colon** - Your numbers are separated by semi-colons (`;`)
* **Colon** - Your numbers are separated by colons (`:`)
* **CRLF** - Carriage return line feed (CRLF) is a control character that originally referred to moving the carriage on typewriters back to the starting position. In computing, it’s used in classic Mac OS and some Windows-based systems to mark the end of a line. If your input uses `\r` as the line-ending character, you can set the delimiter to `\r` to correctly separate values. For example: `100\r200\r300`

## Example

Suppose you want to get the **subtraction** of a series of numbers in your input strings. They are separated by commas (,). To do it:

1. In your Pipeline, open the required [Action](https://docs.onum.com/the-workspace/pipelines/actions) configuration and select the input **Field**.
2. In the **Operation** field, choose **Subtract Operation**.
3. Set **Delimiter** to `Comma`.
4. Give your **Output field** a name and click **Save**. You'll get the subtraction of the numbers in your input data. For example:

```
10, 5, 2 -> 3
```
