stdarch_x86_avx512_f16 #127213)Available on (x86 or x86-64) and target feature 
avx512fp16 and x86 only.Expand description
Multiply the lower complex numbers in a by the complex conjugates of the lower complex numbers in b,
and store the results in dst. 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: use- MXCSR.RC- see- _MM_SET_ROUNDING_MODE
