# divide(_:_:)

Returns the single-precision element-wise division of a scalar value and a vector.

## Declaration

```swift
static func divide<U>(_ scalar: Float, _ vector: U) -> [Float] where U : AccelerateBuffer, U.Element == Float
```

## Parameters

- `scalar`: The input scalar value, A.
- `vector`: The input vector, B.

## Mentioned in

Using vDSP for vector-based arithmetic

## Return Value

Return Value The output vector, C.

## Discussion

Discussion This function calculates the element-wise division of scalar value A and vector B, and writes the result to vector C.  for (n = 0; n < N; ++n)     C[n] = A / B[n];

The following code shows an example of using this function:     let a: Float = 100     let b: [Float] = [1, 2, 3, 4, 5]          let c = vDSP.divide(a, b)          // Prints "[100.0, 50.0, 33.33, 25.0, 20.0]".     print(c)
