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

    pub unsafe fn _mm_maskz_max_sd(k: __mmask8, a: __m128d, b: __m128d) -> __m128d

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

Compare the lower double-precision (64-bit) floating-point elements in a and b, store the maximum value in the lower element of dst using zeromask k (the element is zeroed out when mask bit 0 is not set), and copy the upper element from a to the upper element of dst.
