View official documentation
Purpose:
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 ouput.
Result:
__m128
Example:
#include <xmmintrin.h>
#include <stdio.h>
int main() {
__m128 a = _mm_set1_ps(-0.0f);
__m128 b = _mm_set1_ps(1.23f);
__m128 result = _mm_andnot_ps(a, b);
float output[4];
_mm_storeu_ps(output, result);
for (int i = 0; i < 4; i++) {
printf("%f\n", output[i]);
}
return 0;
