[PEPr] Comment on Math::Math_AP_(Re-proposal)

Etienne Kneuss (http://pear.php.net/user/colder) has commented on the proposal for Math::Math_AP_(Re-proposal). Comment: Most of the points of my comment about Math_AP don't seem to be resolved(tests when to break, convergence, algorithms, pi value, ...) . There is still some problem with the algorithms: The validity range of your algorithm that calculates tan(x) is only |x| < Pi/2. You need some tricks to make it available for every x in |R. Same for ArcTan(x), which have a validity range of |x| <= 1. The exp algorithm is highly divergent for negative input, you'll also need some tricks( e^-x = 1/e^x and e^4.8 = (((e^0.6)^2)^2) for example). I will elaborate on this subject only if you need it.
