# Function core::arch::x86_64::_mm512_zextpd256_pd512
[−][src]

    pub unsafe fn _mm512_zextpd256_pd512(a: __m256d) -> __m512d

🔬 This is a nightly-only experimental API. (`stdsimd` #48556)
This is supported on x86-64 and target feature `avx512f` only.

Cast vector of type __m256d to type __m512d; the upper 256 bits of the result are zeroed. This intrinsic is only used for compilation and does not generate any instructions, thus it has zero latency.
