Function core::arch::x86_64::_mm_maskz_rcp14_ss [−][src]
This is supported on x86-64 and target feature
avx512f
only.Expand description
Compute the approximate reciprocal of the lower single-precision (32-bit) floating-point element in b, store the result in the lower element of dst using zeromask k (the element is zeroed out when mask bit 0 is not set), and copy the upper 3 packed elements from a to the upper elements of dst. The maximum relative error for this approximation is less than 2^-14.
