# vDSP_svdiv

Divides a single-precision scalar value by a single-precision vector.

## Declaration

```occ
void vDSP_svdiv(const float *__A, const float *__B, vDSP_Stride __IB, float *__C, vDSP_Stride __IC, vDSP_Length __N);
```

## Parameters

- `__A`: Pointer to single-precision real input scalar.
- `__B`: Single-precision real input vector.
- `__IB`: Stride for B.
- `__C`: Single-precision real output vector.
- `__IC`: Stride for C.
- `__N`: The number of elements to process.

## Discussion

Discussion This function calculates the scalar value A divied by the first N elements of B, writing the result to C:

The operation is:  for (n = 0; n < N; ++n)     C[n] = A / B[n]; The following code shows an example of using vDSP_vsdiv: let stride = vDSP_Stride(1)

var a: Float = 2 let b: [Float] = [1, 2, 4, 5]

let n = vDSP_Length(b.count)

var c = [Float](repeating: 0,                 count: b.count)

vDSP_svdiv(&a,            b, stride,            &c, stride,            n)

// Prints "[2, 1, 0.5, 0.4]" print(c)
