[PD] purepd atan2~ without expr/externals?

[Frank Barknecht]

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
