Function tracing::stdlib::arch::x86_64::_mm512_maskz_scalef_round_pd

pub unsafe fn _mm512_maskz_scalef_round_pd<const ROUNDING: i32>(
    k: u8,
    a: __m512d,
    b: __m512d,
) -> __m512d

🔬This is a nightly-only experimental API. (stdarch_x86_avx512 #111137)

Available on x86-64 only.

Scale the packed double-precision (64-bit) floating-point elements in a using values from b, and store the results in dst using zeromask k (elements are zeroed out when the corresponding mask bit is not set).

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
