pub unsafe fn _mm512_roundscale_round_pd(
    a: __m512d, 
    imm8: i32, 
    sae: i32
) -> __m512d

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

This is supported on x86-64 and target feature avx512f only.

Round packed double-precision (64-bit) floating-point elements in a to the number of fraction bits specified by imm8, and store the results in dst.
Rounding is done according to the imm8[2:0] parameter, which can be one of:
_MM_FROUND_TO_NEAREST_INT // round to nearest
_MM_FROUND_TO_NEG_INF // round down
_MM_FROUND_TO_POS_INF // round up
_MM_FROUND_TO_ZERO // truncate
_MM_FROUND_CUR_DIRECTION // use MXCSR.RC; see _MM_SET_ROUNDING_MODE

Exceptions can be suppressed by passing _MM_FROUND_NO_EXC in the sae parameter. Intel's documentation
