# Float to string

## Description

This operation transforms a float into a string using a Go format string. The provided format is passed to `fmt.Sprintf` to control how the number is rendered. Common examples include:

* `%.1f` → one decimal place (`1` becomes `"1.0"`)
* `%.2f` → two decimal places (`1` becomes `"1.00"`)
* `%e` → scientific notation (`1` becomes `"1.000000e+00"`)

See the [fmt package documentation](https://pkg.go.dev/fmt) for a complete list of formatting verbs and flags.

## Example

Suppose you want to convert a series of float values into strings following a specific format:

1. In your Pipeline, open the required [Action](/pipelines/actions.md) configuration and select the input **Field**.
2. In the **Operation** field, choose **Float to String**.
3. Set **Format** to `%.1f`
4. Give your **Output field** a name and click **Save**. The values in your input field will be transformed into strings according to the given format. For example:

```
Input data - 5.218 

Radix (Base) - "%.1f"

Output data - "5.2"
```
