Purpose:
Broadcast half-precision (16-bit) floating-point value "a" to all elements of "dst".
Result:
__m256h
Example:
#include <stdio.h>
#include <immintrin.h>
int main() {
_Float16 value = 42.0f;
__m256h result = _mm256_set1_ph(value);
_Float16 output[16];
_mm256_storeu_ph(output, result);
printf("Input value: %.1f\n", (float)value);
printf("Result vector: {
");
for(int i = 0; i < 15; i++) {
printf("%.1f, ", (float)output[i]);
}
printf("%.1f
}
\n", (float)output[15]);
return 0;
