I have a problem with  atan2(a,b) when b = zero.

The documentation on the page 
<http://www.povray.org/documentation/view/3.7.1/228/> says :

Arc-tangent of (A/B). Returns the angle, measured in radians, whose 
tangent is (A/B). **Returns appropriate value even if B is zero**

In my case, i get : Parse Error: Domain error in atan2!

So it's up to me to test if b=zero and return the appropriate value ?
