# EXP function

## Description

Raises the mathematical constant e to the given power. e is Euler’s number (roughly equal to 2.71828), also known as the base of the natural logarithm. It is the opposite of the `LN` function.

## Syntax

`EXP(Power)`

## Arguments

| Argument | Type | Dimensions | Description |
| --- | --- | --- | --- |
| *Power* (required) | Number | Any Dimensions | The exponent applied to e. |

## Returns

| Type | Dimensions |
| --- | --- |
| Number | Dimensions of *Power* |

## Examples

| Formula | Result | Description |
| --- | --- | --- |
| `EXP(1)` | 2.71828... | e^1 roughly equals 2.71828 |
| `EXP(3.3)` | 27.11264... | e^3.3 roughly equals 27.11264 |
| `EXP(-1.2)` | 0.30119... | e^-1.2 roughly equals 0.30119 |
| `EXP(LN(3))` | 3 | As `EXP` and `LN` perform inverse operations, the output is the same as the input. |
