Function core::arch::x86_64::_mm_cvti64_sd

pub unsafe fn _mm_cvti64_sd(a: __m128d, b: i64) -> __m128d

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

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

Convert the signed 64-bit integer 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.
