-   View InfluxDB support

`math.pow()` returns `x**y`, the base-x exponential of `y`.

##### Function type signature

```js
(x: float, y: float) => float
```

For more information, see [Function type signatures](/flux/v0/function-type-signatures/).

## Parameters

### x

(Required) Base value to operate on.

### y

(Required) Exponent value.

## Examples

-   [Return the base-x exponential of a value](#return-the-base-x-exponential-of-a-value)
-   [Use math.pow in map](#use-mathpow-in-map)

### Return the base-x exponential of a value

```js
import "math"

math.pow(x: 2.0, y: 3.0)// 8.0

```

### Use math.pow in map

```js
import "math"

data
    |> map(fn: (r) => ({_time: r._time, _value: math.pow(x: r.t1, y: r.t2)}))
```
