# raiseToPower(_:)

Replaces all values in the noise field by raising each value to the specified power.

## Declaration

```swift
func raiseToPower(_ power: Double)
```

## Parameters

- `power`: The exponent to raise each noise value to.

## Discussion

Discussion Noise values range from -1.0 to 1.0, so exponentiating always results in lower values than in the original noise, with a greater effect on low original values than on high values.
