Function _mm256_cvtps_ph
#[target_feature(enable = "f16c")]
pub fn _mm256_cvtps_ph(a: __m256, IMM_ROUNDING: i32) -> __m128iConverts the 8 x 32-bit float values in the 256-bit vector a into 8 x
16-bit half-precision float values stored in a 128-bit wide vector.
Rounding is done according to the imm_rounding parameter, which can be one of:
_MM_FROUND_TO_NEAREST_INT: round to nearest_MM_FROUND_TO_NEG_INF: round down_MM_FROUND_TO_POS_INF: round up_MM_FROUND_TO_ZERO: truncate_MM_FROUND_CUR_DIRECTION: useMXCSR.RC- see_MM_SET_ROUNDING_MODE
