Hm-hm. Why not use this?
<pre><code>function fmod (x, y) {
    return  x % y;
}</code></pre>

The following comments should be removed, they are not true:

// %          note: Examples in PHP &amp;amp; JS return: 0.8, but according 
    // %          note: the PHP-manual's it should be 0.5. PHP manual seems to be incorrect?

The example 1 at rad2deg is wrong. It should be something like:

rad2deg (3.141592653589793)
returns 180

Two simple functions that translate deg to rad and viceversa:

<pre><code>
function deg2rad(angle)
  {
  //*        example 1 : deg2rad (180)
  //*        returns 1 : 3.141592653589793
  return (angle/180)*Math.PI;
  }
  
function rad2deg(angle)
  {
  //*        example 1 : deg2rad (pi())   
  //*        returns 1 : 3.141592653589793
  return (angle/Math.PI)*180;
  }
</code></pre>
