# Sum
## Description
This operation calculates the sum of a series of numbers provided as input, separated by a specified delimiter. It is a simple yet powerful tool for numerical data analysis, enabling quick summation of datasets or values.
***
## Data types
These are the input/output expected data types for this operation:
### Input data
 - Input string containing numbers to sum, separated by a specified delimiter.
### Output data
 - The result of the total sum.
***
## Parameters
These are the parameters you need to configure to use this operation (mandatory parameters are marked with a **\***):
Delimiter*
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 **sum** 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](/the-workspace/pipelines/actions.md) configuration and select the input **Field**.
2. In the **Operation** field, choose **Sum Operation**.
3. Set **Delimiter** to `Comma`.
4. Give your **Output field** a name and click **Save**. You'll get the sum of the numbers in your input data. For example:
```
10, 5, 2 -> 17
```
{% hint style="info" %}
You can try out operations with specific values using the **Input** field above the operation. You can enter the value in the example above and check the result in the **Output** field.
{% endhint %}

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:
```
GET https://docs.onum.com/the-workspace/pipelines/actions/transformation/field-transformation/field-transformation-operations/arithmetic-logic/sum.md?ask=&goal=
```
`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.
Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
