🔬 This is a nightly-only experimental API. (stdsimd)
This is supported on x86-64 and target feature avx512f,avx512vl only.
Expand description

Multiply packed single-precision (32-bit) floating-point elements in a and b, subtract packed elements in c from the negated intermediate result, and store the results in dst using zeromask k (elements are zeroed out when the corresponding mask bit is not set).
