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

    pub unsafe fn _mm_mask_fixupimm_round_sd(
        a: __m128d,
        k: __mmask8,
        b: __m128d,
        c: __m128i,
        imm8: i32,
        sae: i32
    ) -> __m128d

🔬 This is a nightly-only experimental API. (`stdsimd` #48556)
This is supported on x86-64 and target feature `avx512f` only.

Fix up the lower double-precision (64-bit) floating-point elements in a and b using the lower 64-bit integer in c, store the result in the lower element of dst using writemask k (the element is copied from a when mask bit 0 is not set), and copy the upper element from a to the upper element of dst. imm8 is used to set the required flags reporting.

Exceptions can be suppressed by passing _MM_FROUND_NO_EXC in the sae parameter. Intel's documentation
