performance optimization regarding double/float and passing parameters
<p>I replaced all doubles with floats in my project, which resulted in performance improvement.</p>

<p>All my functions now, take arguments not as references. If I pass them as references I would save one copy. As you know, parameters if not passed as reference, are copied in the function.</p>

<p>I was wondering if that is worth it doing for like 200 functions, and should I expect improvements?</p>

<p>Thank you</p>
