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 zeromask k (the element is zeroed out 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
