Function core::arch::x86::_mm512_maskz_roundscale_round_ps

pub unsafe fn _mm512_maskz_roundscale_round_ps(
    k: __mmask16, 
    a: __m512, 
    const IMM8: i32, 
    const SAE: i32
) -> __m512

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

Available on x86 and target feature avx512f only.

Round packed single-precision (32-bit) floating-point elements in a to the number of fraction bits specified by imm8, 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 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
