Function serde::lib::core::arch::x86_64::_mm512_cvt_roundepu64_pd

pub unsafe fn _mm512_cvt_roundepu64_pd<const ROUNDING: i32>(
    a: __m512i,
) -> __m512d

🔬This is a nightly-only experimental API. (stdarch_x86_avx512)

Available on x86-64 only.

Convert packed unsigned 64-bit integers in a to packed double-precision (64-bit) floating-point elements, and store the results 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                       // use MXCSR.RC
