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

1q = foreach q generate exp(value) as value;
2q = filter q by exp(value) < 5;
