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

    pub unsafe fn _mm_maskz_sub_ss(k: __mmask8, a: __m128, b: __m128) -> __m128

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

Subtract the lower single-precision (32-bit) floating-point element in b from the lower single-precision (32-bit) floating-point element in a, store the result 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 3 packed elements from a to the upper elements of dst.
