[−][src]

    pub unsafe fn _mm_cvt_roundss_sd<const SAE: i32>(
        a: __m128d,
        b: __m128
    ) -> __m128d

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

Convert the lower single-precision (32-bit) floating-point element in b to a double-precision (64-bit) floating-point element, store the result in the lower element of dst, and copy the upper element from a to the upper element of dst.
Exceptions can be suppressed by passing _MM_FROUND_NO_EXC in the sae parameter.
