pub unsafe fn _mm_maskz_sub_ss(k: u8, a: __m128, b: __m128) -> __m128🔬This is a nightly-only experimental API. (
stdsimd)Available on x86-64 only.
Expand description
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.
