# 1.27.0[−][src]Function core::arch::x86_64::_mm256_rsqrt_ps

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

This is supported on x86-64 and target feature `avx` only.

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