Function core::arch::x86::_mm256_rsqrt_ps

pub unsafe fn _mm256_rsqrt_ps(a: __m256) -> __m256

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

This is supported on x86 and target feature avx only.

Compute the approximate reciprocal square root of packed single-precision (32-bit) floating-point elements in a, and return the results. The maximum relative error for this approximation is less than 1.5*2^-12.
