🔬This is a nightly-only experimental API. (
stdsimd
#48556)Available on (x86 or x86-64) and target feature
avx512f
and x86-64 only.Expand description
Multiply the lower single-precision (32-bit) floating-point elements in a and b, and add the intermediate result to the lower element in c. Store the result in the lower element of dst using writemask k (the element is copied from a when mask bit 0 is not set), and copy the upper 3 packed elements from a to the upper elements of dst.
