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. | ## See also Excel: [EXP](https://support.microsoft.com/en-us/office/exp-function-c578f034-2c45-4c37-bc8c-329660a63abe) Related articles: [LOG](/v1/docs/log-function), [LN](/v1/docs/ln-function)
