# Function core::arch::x86_64::_mm512_cmpnlt_pd_mask
[−][src]

    pub unsafe fn _mm512_cmpnlt_pd_mask(a: __m512d, b: __m512d) -> __mmask8

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

Compare packed double-precision (64-bit) floating-point elements in a and b for not-less-than, and store the results in mask vector k.
