Computes approximate reciprocals of square roots of float32 values.The corresponding Intel® AVX instruction is VRSQRTPS.
extern __m256 _mm256_rsqrt_ps(__m256 a); |
a |
float32 source vector |
Performs a computation of the reciprocal of the square roots of eight single-precision floating point elements of the source vector a and returns the result as a vector.
Result of the reciprocal square root operation.
