# vvcospif(_:_:_:)

Calculates the cosine of pi multiplied by each element in an array of single-precision values.

## Declaration

```swift
func vvcospif(_: UnsafeMutablePointer<Float>, _: UnsafePointer<Float>, _: UnsafePointer<Int32>)
```

## Discussion

Discussion Parameters: The following code shows an example of using vvcospif(_:_:_:). float x[] = {-0.5, 0, 0.5}; float y[3]; int n = 3;   vvcospif(y, x, &n);   NSLog(@"y: [%lf, %lf, %lf]", y[0], y[1], y[2]);
