Function _mm512_maskz_cvt_roundpd_ph

pub unsafe fn _mm512_maskz_cvt_roundpd_ph(
    k: __mmask8,
    a: __m512d,
    const ROUNDING: i32,
) -> __m128h

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

Available on (x86 or x86-64) and target feature avx512fp16 and x86-64 only.

Convert packed double-precision (64-bit) floating-point elements in a to packed half-precision (16-bit) floating-point elements, and store the results in dst using zeromask k (elements are zeroed out when the corresponding mask bit 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 : use MXCSR.RC - see _MM_SET_ROUNDING_MODE
