# absolute(_:result:)

Calculates the absolute value of each element in the supplied single-precision vector.

## Declaration

```swift
static func absolute<U, V>(_ vector: U, result: inout V) where U : AccelerateBuffer, V : AccelerateMutableBuffer, U.Element == Float, V.Element == Float
```

## Parameters

- `vector`: The source vector.
- `result`: On output, the absolute values of the elements in the source vector.

## Discussion

Discussion For example, the following code calculates the absolute values of the elements of an array:     let values: [Float] = [-1, 2, -3, 4, -5, 6, -7, 8]          let absoluteValues = [Float](unsafeUninitializedCapacity: values.count) {         buffer, initializedCount in                  vDSP.absolute(values, result: &buffer)                  initializedCount = values.count     }          // Prints "[1.0, 2.0, 3.0, 4.0, 5.0, 6.0, 7.0, 8.0]".     print(absoluteValues)
