stdarch_x86_avx512 #111137)Available on (x86 or x86-64) and target feature 
avx512f and x86-64 only.Expand description
Multiply packed double-precision (64-bit) floating-point elements in a and b, add the intermediate result to packed elements in c, and store the results in dst using zeromask k (elements are zeroed out when the corresponding mask bit is not set).\
Rounding is done according to the rounding[3:0] 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
