Function core::arch::x86_64::_mm_rcp14_sd
source · pub unsafe fn _mm_rcp14_sd(a: __m128d, b: __m128d) -> __m128d🔬This is a nightly-only experimental API. (
stdsimd #48556)Available on (x86 or x86-64) and target feature
avx512f and x86-64 only.Expand description
Compute the approximate reciprocal of the lower double-precision (64-bit) floating-point element in b, store the result in the lower element of dst, and copy the upper element from a to the upper element of dst. The maximum relative error for this approximation is less than 2^-14.
