Function _mm256_cvtps_ph

pub unsafe fn _mm256_cvtps_ph(a: __m256, const IMM_ROUNDING: i32) -> __m128i

Available on (x86 or x86-64) and target feature f16c and x86-64 only.

Converts 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 | _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.
