CGAffineTransformMakeRotation() Question
<p>I was wondering which of the following is less expensive on memory? I noticed you can leave out the *M_PI portion and it still will work fine. Does this mean if saves some calculations as well or does it matter?</p>

<p>Example:</p>

<p>CGAffineTransformMakeRotation(0.5*M_PI);</p>

<p>Or other example:</p>

<p>CGAffineTransformMakeRotation(0.7); for example. </p>

<p>I would think the last example is more efficient because it doesn't have to multiply by PI or am I wrong in assuming that? </p>

<p>Over all I don't think either one is over powering and a big memory suck I just was curious about what is happening under the hood. </p>
