# From base

## Description

This operation converts a number from a specified base (or radix) into its decimal form (base 10), represented as a string.

In a positional numeral system, the radix or base is the number of unique digits, including the digit zero, used to represent numbers. For example, (100)<sub>10</sub> is equivalent to 100 (the decimal system is implied in the latter) and represents the number one hundred, while (100)<sub>2</sub> (in the binary system with base 2) represents the number four.

## Data types

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

### Input data

![](/files/PLlLS9WDthpZu0nbKCNG) - The input numbers you want to transform.

### Output data

![](/files/FiO6hMIDNPuoHDSTAxHC) - Resulting decimal forms represented as strings, considering the specified base.

## 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>Radix (Base)<mark style="color:red;"><strong>*</strong></mark></summary>

Enter the base of the input numbers. Must be a value between `2` and `36`.

## Example

Suppose you want to **transform** a series of numbers with a specified **base** into their decimal forms:

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 **From Base**.
3. Set **Radix (Base)** to `2`.
4. Give your **Output field** a name and click **Save**. The values in your input field will be decoded. For example:

```
Input data - "100"

Radix (Base) - 2

Output data - "4"
```

{% 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 %}
