Function core::arch::x86_64::_mm_max_round_sd

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

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

This is supported on x86-64 and target feature avx512f only.

Compare the lower double-precision (64-bit) floating-point elements in a and b, store the maximum value 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.
