# String to float

## Description

This operation converts a numeric string into a float value. The input string must represent a valid floating-point number (e.g., `3.14` or `1e-2`). The conversion supports both decimal and scientific notations.

***

## Data types

These are the input/output expected data types for this operation:

### Input data

`String` - String of separated values to be transformed. You must enter the separator in the parameter below.

### Output data

`Float` - Resulting values after transforming them into a list of comma-separated values.

***

## Example

Suppose you want to convert a series of **strings** into their **corresponding float values**:

1. In your Pipeline, open the required [Action](https://onum.gitbook.io/onum-docs/the-workspace/pipelines/actions) configuration and select the input **Field**.
2. In the **Operation** field, choose **String to float**.
3. Give your **Output field** a name and click **Save**. The numeric string values in your input field will be transformed into float values. For example:

<pre><code><strong>"3.14" -> 3.14
</strong></code></pre>

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.
