View official documentation
Purpose:
Compute the bitwise NOT of packed single-precision (32-bit) floating-point elements in a and then AND with b, and store the results in output.
Result:
__m256
Example:
#include <immintrin.h>
#include <stdio.h>
int main() {
__m256 a = _mm256_set1_ps(-0.0f);
__m256 b = _mm256_set1_ps(1.23f);
__m256 result = _mm256_andnot_ps(a, b);
float output[8];
_mm256_storeu_ps(output, result);
for (int i = 0; i < 8; i++) {
printf("%f\n", output[i]);
}
return 0;
