Description: Returns the square root of each value in the input. Use when you need the square root of positive values for scaling, normalization, or mathematical transformations.
**Category:** [Math & numeric](/math-numeric/)

## Overview

The **SQRT** function **returns the square root of each value in the input**.

Use this function when you need the square root of positive values for scaling, normalization, or mathematical transformations.

## Syntax

`SQRT('Node')`

## Parameters

| Parameter | Description                                                                   | Type           | Required |
| --------- | ----------------------------------------------------------------------------- | -------------- | -------- |
| **Node**  | Input node, specified using the node name in single quotes (e.g. `'Profit'`). | Node reference | Yes      |

## Watch out

* Use [POWER](/power/) for other roots (e.g. cube roots via a fractional exponent).

## Example

### Square root of positive input values

This example shows the square root computed for a node with simple positive values. Each result is the square root of the corresponding input value.

**Input node:** `'A'`
