Description: Returns Euler's number, e (~2.718) raised to a power of the given value, while retaining all dimensions. Use this when you need to compute e raised to the power of node values, for example in continuous growth or compounding models.

## Overview

The **EXP** function **returns Euler's number, e (\~2.718) raised to a power of the given value**, while retaining all dimensions.

Use this function when you need to compute e raised to the power of node values, for example in continuous growth or compounding models.

## Syntax

`EXP('Node')`

## Parameters

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

## Example

### Exponential transformation of node values

This example computes e raised to the power of each value in the input node.

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