Function no_std_compat::arch::x86_64::_mm512_mask_fnmadd_round_ps

pub unsafe fn _mm512_mask_fnmadd_round_ps<const ROUNDING: i32>(
    a: __m512,
    k: u16,
    b: __m512,
    c: __m512,
) -> __m512

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

Available on x86-64 only.

Multiply packed single-precision (32-bit) floating-point elements in a and b, add the negated intermediate result to packed elements in c, and store the results in dst using writemask k (elements are copied from a 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
