Function _mm512_mask_cvt_roundpd_ph

pub unsafe fn _mm512_mask_cvt_roundpd_ph<const ROUNDING: i32>(
    src: __m128h,
    k: u8,
    a: __m512d,
) -> __m128h

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

Available on 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 writemask k (elements are copied from src to dst 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
