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

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