 Location: Arithmetic  >  Vector Add
Purpose:
Add packed double-precision (64-bit) floating-point elements in a and b
Result:

A 256-bit vector that contains the result of the addition.

Example:
#include <immintrin.h>
#include <stdio.h>
int main() {
 __m256d a = _mm256_set_pd(1.5, 2.5, 3.5, 4.5);
 __m256d b = _mm256_set_pd(4.0, 3.0, 2.0, 1.0);
 __m256d result = _mm256_add_pd(a, b);
 double* res = (double*)&result;
 for (int i = 0; i < 4; ++i) {
   printf("%f ", res[i]);
  }
  printf("\n");

  return 0;
 }
