Function wasmer_types::entity::__core::arch::x86_64::_mm_mask_roundscale_round_sd[−][src]

pub unsafe fn _mm_mask_roundscale_round_sd(
    src: __m128d, 
    k: u8, 
    a: __m128d, 
    b: __m128d, 
    imm8: i32, 
    sae: i32
) -> __m128d

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

This is supported on x86-64 and 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 writemask k (the element is copied from src 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

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