    pub unsafe fn _mm_cvt_roundsh_i32(a: __m128h, const ROUNDING: i32) -> i32

🔬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.
Expand description

Convert the lower half-precision (16-bit) floating-point element in a to a 32-bit integer, and store the result 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
