title: What is the difference between _mm_set1_ps and _mm_set_ps1?
body: <p>Is there any difference between these functions? If not, why?</p>
  
  <pre><code>__m128 __mm_set1_ps(float a)
  __m128 __mm_set_ps1(float a)
  </code></pre>
  
  <p>Both descriptions are the same on the <a href="https://software.intel.com/sites/landingpage/IntrinsicsGuide/#text=_mm_set" rel="nofollow noreferrer">Intel Intrinsics Guide</a> website.
  Thank you.</p>
