Function core::arch::x86_64::_mm512_cvt_roundps_epi32

pub unsafe fn _mm512_cvt_roundps_epi32(
    a: __m512,
    const ROUNDING: i32
) -> __m512i

🔬This is a nightly-only experimental API. (stdsimd #48556)

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

将包装的单精度 (32-bit) 浮点元素转换为包装的 32 位整数，并将结果存储在 dst 中。

根据 rounding[3: 0] 参数进行舍入，该参数可以是以下之一： (_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; 请参见 _MM_SET_ROUNDING_MODE
