Function _mm512_cvt_roundph_epi16 

pub fn _mm512_cvt_roundph_epi16(a: __m512h, const ROUNDING: i32) -> __m512i

🔬This is a nightly-only experimental API. (stdarch_x86_avx512_f16 #127213)

Available on x86 and target feature avx512fp16 only.

Convert packed half-precision (16-bit) floating-point elements in a to packed 16-bit integers, and store the results in dst.

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 : use MXCSR.RC - see _MM_SET_ROUNDING_MODE
