View official documentation
Purpose:
Finds the absolute value of each packed double-precision (64-bit) floating-point element in a, storing the results in output.
Result:
A 512-bit vector of 8 x 64-bit double-precision floating-point numbers that hold the absolute values of the input elements.
Example:
#include <immintrin.h>
#include <stdio.h>
int main() {
__m512d v2 = _mm512_set_pd(-1.0, 2.0, -3.0, 4.0, -5.0, 6.0, -7.0, 8.0);
__m512d result = _mm512_abs_pd(v2);
double result_data[8];
_mm512_storeu_pd(result_data, result);
for (int i = 0; i < 8; i++) {
printf("%f ", result_data[i]);
}
printf("\n");
return 0;
