# power(m, n)

Returns *m* raised to the *n_th power. \_m*, *n* can be any numeric value in the range of -1e308 <= *m*, *n* <= 1e308. Returns `null` if *m* = 0 and *n* < 0. This function can only be used in a `foreach` statement.

- If *m* = 0, *n* must be a non-negative value.
- If *m* < 0, *n* must be an integer value.
- The result of power(*m*, *n*) must be within the range expressed by a float64 number.

## Example

```nolang
q = foreach q generate power(length, 2) as area, length;
q = filter q by power(length, 2) > 10;
```
