[PD] purepd atan2~ without expr/externals?

[padawan12 at obiwannabe.co.uk]

A way to attack it might be to find a continued fraction form
like I did for tanh, about 4 or 5 terms was an adequate approximation.



Hi,

I'd like to use a signal [atan2~] in a Pd without externals nor
[expr~] (i.e.  inn RjDj). Does anyone have a purepd implementation of
it or maybe a pointer to some math/trigonometric
identity/ln-substituion formula for atan2?

Ciao
