Function core::arch::x86_64::_mm512_mask_sub_round_ps

pub unsafe fn _mm512_mask_sub_round_ps(
    src: __m512,
    k: __mmask16,
    a: __m512,
    b: __m512,
    const ROUNDING: i32
) -> __m512

🔬This is a nightly-only experimental API. (stdsimd #48556)

Available on (x86 or x86-64) and target feature avx512f and x86-64 only.

Subtract packed single-precision (32-bit) floating-point elements in b from packed single-precision (32-bit) floating-point elements in a, and store the results in dst using writemask k (elements are copied from src 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
