View official documentation
Purpose:
Add 4 each element in 4 x single-precision (32-bit) floating-point elements in a and b, and store the results in output.
Result:
A vector of 4 x 32-bit single-precision floats.
Example:
#include <xmmintrin.h>
#include <stdio.h>
int main() {
__m128 a = _mm_set_ps(1.0f, 2.0f, 3.0f, 4.0f);
__m128 b = _mm_set_ps(4.0f, 3.0f, 2.0f, 1.0f);
__m128 result = _mm_add_ps(a, b);
float* res = (float*)&result;
for (int i = 0; i < 4; ++i) {
printf("%f ", res[i]);
}
printf("\n");
return 0;
}Prototypes
