stdarch_x86_avx512_f16 #127213)Available on (x86 or x86-64) and target feature
avx512fp16 and x86 only.Expand description
Multiply packed complex numbers in a and b, accumulate to the corresponding complex numbers in c,
and store the results in dst using writemask k (the element is copied from a when the corresponding mask
bit is not set). Each complex number is composed of two adjacent half-precision (16-bit) floating-point
elements, which defines the complex number complex = vec.fp16[0] + i * vec.fp16[1].
Rounding is done according to the rounding parameter, which can be one of:
_MM_FROUND_TO_NEAREST_INT|_MM_FROUND_NO_EXC: round to nearest and suppress exceptions_MM_FROUND_TO_NEG_INF|_MM_FROUND_NO_EXC: round down and suppress exceptions_MM_FROUND_TO_POS_INF|_MM_FROUND_NO_EXC: round up and suppress exceptions_MM_FROUND_TO_ZERO|_MM_FROUND_NO_EXC: truncate and suppress exceptions_MM_FROUND_CUR_DIRECTION: useMXCSR.RC- see_MM_SET_ROUNDING_MODE
