    Question Algorithms: x,y values convert to angle.

    &lt;div&gt;Hi i am new on the forum. I am making a smartphone application and this is the first time iím working with algorithms.&lt;/div&gt;&lt;div&gt;I am looking for algorithms that can convert &amp;nbsp;x and y value on a Cartesian plane (x,y) to an angle. &amp;nbsp;The angle can be 0-360 degrees or 0-2π radian.&amp;nbsp;&lt;/div&gt;&lt;div&gt;&lt;br&gt;&lt;/div&gt;&lt;div&gt;Does anyone know of such algorithms?&lt;/div&gt;&lt;div&gt;I have looked for geometric algorithms on Google. I have also found a list of algorithms on Wikipedia, but no luck finding this particular algorithm.&lt;/div&gt;&lt;div&gt;Also are there search databases that solely contain algorithms?&lt;/div&gt;&lt;div&gt;Thank you in Advance.&amp;nbsp;&lt;br&gt;&lt;br&gt;Here can you see a simple visual representation:&lt;/div&gt;&lt;div&gt;<img src="http://i50.tinypic.com/34g6g3m.jpg" border="0" alt="">&lt;/div&gt;&lt;div&gt;<a href="http://tinypic.com/view.php?pic=34g6g3m&amp;amp;s=6" target="_blank">http://tinypic.com/view.php?pic=34g6g3m&amp;amp;s=6</a>&lt;br&gt;&lt;br&gt;&lt;/div&gt;&lt;div&gt;&lt;br&gt;&lt;/div&gt;

    Please don't use "special symbols". It is impossible to read that.
