Function _mm512_maskz_cvt_roundps_ph

pub fn _mm512_maskz_cvt_roundps_ph(
    k: __mmask16,
    a: __m512,
    const ROUNDING: i32,
) -> __m256i

Available on (x86 or x86-64) and target feature avx512f and x86 only.

Convert packed single-precision (32-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[3:0] 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 // use MXCSR.RC; see _MM_SET_ROUNDING_MODE
• _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 | _MM_FROUND_NO_EXC // use MXCSR.RC and suppress exceptions; see _MM_SET_ROUNDING_MODE
