stdarch_x86_avx512_f16 #127213)Available on (x86 or x86-64) and target feature 
avx512fp16 and x86-64 only.Expand description
Multiply packed half-precision (16-bit) floating-point elements in a and b, subtract the intermediate result from packed elements in c, and store the results in dst using zeromask k (the element is zeroed out when the corresponding mask bit is not set).
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
