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
