# [−][src]Function core::arch::x86::_mm512_fmaddsub_pd

    pub unsafe fn _mm512_fmaddsub_pd(a: __m512d, b: __m512d, c: __m512d) -> __m512d

🔬 This is a nightly-only experimental API. (`stdsimd` #48556)
This is supported on x86 and target feature `avx512f` only.

Multiply packed double-precision (64-bit) floating-point elements in a and b, alternatively add and subtract packed elements in c to/from the intermediate result, and store the results in dst.
