Function core::arch::x86_64::_mm_mask_rcp14_sd   [−][src]
pub unsafe fn _mm_mask_rcp14_sd(
    src: __m128d, 
    k: __mmask8, 
    a: __m128d, 
    b: __m128d
) -> __m128dThis is supported on x86-64 and target feature 
avx512f 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 using writemask k (the element is copied from src when mask bit 0 is not set), 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.
