[−][src]

    pub unsafe fn _mm_maskz_fnmsub_ss(
        k: __mmask8,
        a: __m128,
        b: __m128,
        c: __m128

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

Multiply the lower single-precision (32-bit) floating-point elements in a and b, and subtract the lower element in c from the negated intermediate result. 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.
