# Function core::arch::x86_64::_mm512_maskz_roundscale_round_ps[−][src]

    pub unsafe fn _mm512_maskz_roundscale_round_ps(
        k: __mmask16,
        a: __m512,
        imm8: i32,
        sae: i32
    ) -> __m512

🔬 This is a nightly-only experimental API. (`stdsimd` #48556)
This is supported on x86-64 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
