# exp(n)

Returns the value of Euler's number *e* raised to the power of *n*, where *e* = 2.71828183… The smallest value for *n* that doesn’t result in 0 is 3e-324. *n* can be any real numeric value in the range of -1e308 <= n <= 700. This function can only be used in a `foreach` statement.

## Example

```nolang
q = foreach q generate exp(value) as value;
q = filter q by exp(value) < 5;
```
