pub fn _mm_cvt_roundu64_sd(a: __m128d, b: u64, const ROUNDING: i32) -> __m128d🔬This is a nightly-only experimental API. (
stdarch_x86_avx512 #111137)Available on x86-64 and target feature
avx512f only.Expand description
Convert the unsigned 64-bit integer b to a double-precision (64-bit) floating-point element, store the result in the lower element of dst, and copy the upper element from a to the upper element of dst.
Rounding is done according to the rounding[3:0] 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: useMXCSR.RC- see_MM_SET_ROUNDING_MODE
