# add(_:_:)

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

## Declaration

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

## Parameters

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

## Mentioned in

Using vDSP for vector-based arithmetic

## Return Value

Return Value The output vector, C.

## Discussion

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

The following code shows an example of using this function:     let a: [Float] = [1, 2, 3, 4, 5]     let b: Float = 10          let c = vDSP.add(b, a)          // Prints "[11.0, 22.0, 33.0, 44.0, 55.0]".     print(c)
