f16c only.Expand description
Converts the 4 x 32-bit float values in the 128-bit vector a into 4 x
16-bit half-precision float values stored in the lowest 64-bit of a 128-bit
vector.
Rounding is done according to the imm_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- see_MM_SET_ROUNDING_MODE.
