Expand description
Divide the lower half-precision (16-bit) floating-point elements in a by b, store the result in the lower element of dst, and copy the upper 7 packed elements from a to the upper elements of dst using writemask k (the element is copied from src when mask bit 0 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
: useMXCSR.RC
