Function core::arch::x86::_mm_maskz_rsqrt14_ps [−][src]
This is supported on x86 and target feature
avx512f,avx512vl
only.Expand description
Compute the approximate reciprocal square root of packed single-precision (32-bit) floating-point elements in a, and store the results in dst using zeromask k (elements are zeroed out when the corresponding mask bit is not set). The maximum relative error for this approximation is less than 2^-14.
