Purpose:
Compute the square root of packed single-precision (32-bit) floating-point elements in a, and store the results in output.
Result:
__m128
Example:
#include <xmmintrin.h>
#include <stdio.h>
int main() {
__m128 a = _mm_set_ps(16.0f, 9.0f, 4.0f, 1.0f);
__m128 result = _mm_sqrt_ps(a);
float res[4];
_mm_storeu_ps(res, result);
printf("%f %f %f %f\n", res[0], res[1], res[2], res[3]);
return 0;
