# vDSP_fft5_zopD

Computes a double-precision out-of-place radix-5 complex FFT, either forward or inverse.

```
extern void vDSP_fft5_zopD(FFTSetupD __Setup, const DSPDoubleSplitComplex *__A, vDSP_Stride __IA, const DSPDoubleSplitComplex *__C, vDSP_Stride __IC, vDSP_Length __Log2N, FFTDirection __Direction);
```

## Discussion

The number of input and output values processed equals 5 times the power of 2 specified by parameter `Log2N`.

This is the same as [`vDSP_fft5_zop`](/documentation/Accelerate/vDSP_fft5_zop), except for the types of the `Setup` object and the `A` and `C` vectors.

See also functions  [`vDSP_create_fftsetupD`](/documentation/Accelerate/vDSP_create_fftsetupD), [`vDSP_destroy_fftsetupD`](/documentation/Accelerate/vDSP_destroy_fftsetupD), and [vDSP Programming Guide](https://developer.apple.com/library/archive/documentation/Performance/Conceptual/vDSP_Programming_Guide/Introduction/Introduction.html#//apple_ref/doc/uid/TP40005147).
