# vDSP_vfix16

Converts an array of single-precision floating-point values to signed 16-bit integer values, rounding toward zero.

## Declaration

```occ
void vDSP_vfix16(const float *vDSP_input1, ptrdiff_t vDSP_stride1, int16_t *vDSP_input2, ptrdiff_t vDSP_stride2, size_t vDSP_size);
```

## Parameters

- `__A`: The single-precision floating-point input vector.
- `__IA`: The stride for input vector A.
- `__C`: The 16-bit integer output vector.
- `__IC`: The stride for output vector C.
- `__N`: The number of values to convert.

## Discussion

Discussion If the resulting value is outside the bounds of the output type, the behavior is undefined. If you need to handle out-of-bounds data, use one of the functions under the “Clipping Operations” topic of Clipping, limit, and threshold operations.
