There are two approximations here: http://www.dspguru.com/comp.dsp/tricks/alg/fxdatan2.htm
a rough implementation is attached. I haven't listened to these yet though, so not sure how they sound.

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
