Function surgeshaper_asym::imports::imports::_mm_maskz_roundscale_sd

pub unsafe fn _mm_maskz_roundscale_sd<const IMM8: i32>(
    k: u8, 
    a: __m128d, 
    b: __m128d
) -> __m128d

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

This is supported with target feature avx512f only.

Round the lower double-precision (64-bit) floating-point element in b to the number of fraction bits specified by imm8, store the result in the lower element of dst using zeromask k (the element is zeroed out when mask bit 0 is not set), and copy the upper element from a to the upper element of 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
