# vDSP_vsmfix24

Scales and converts single-precision floating-point values to signed 24-bit integer values.

## Declaration

```occ
void vDSP_vsmfix24(const float vDSP_input1[], ptrdiff_t vDSP_stride1, const float vDSP_input2[], vDSP_int24 *vDSP_input3, ptrdiff_t vDSP_stride2, size_t vDSP_size);
```

## Parameters

- `__A`: The single-precision floating-point input vector.
- `__IA`: The stride for input vector A.
- `__B`: A pointer to a floating-point scaling factor.
- `__C`: The signed 24-bit integer output vector.
- `__IC`: The stride for output vector C.
- `__N`: The number of values to convert.
