Function wiwi::rust_core::arch::x86_64::_mm_cvt_roundsh_u64

pub unsafe fn _mm_cvt_roundsh_u64<const ROUNDING: i32>(a: __m128h) -> u64

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

Available on x86-64 only.

Convert the lower half-precision (16-bit) floating-point element in a to a 64-bit unsigned 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
