Function _mm_cvt_roundsd_u64

pub unsafe fn _mm_cvt_roundsd_u64<const ROUNDING: i32>(a: __m128d) -> u64

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

Available on x86-64 only.

Convert the lower double-precision (64-bit) floating-point element in a to an unsigned 64-bit integer, and store the result in 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 : use MXCSR.RC - see _MM_SET_ROUNDING_MODE
