public class CartesianToPolar extends TypedAtomicActor
Convert a Cartesian pair, which is represented by two double tokens (x and y), to a polar form, which is also represented by two double tokens (magnitude and angle). The angle is in radians.
The implementation uses java.lang.Math.atan2(double, double).

Construct an actor with the given container and name.

|---|---|
void |
fire()
Consume one double token from each of the two input ports (x and y),
and output one new double token on each of the two output ports
(magnitude and angle).
|
boolean |
prefire()
Return false if either of the input ports has no token, otherwise
return what the superclass returns (presumably true).
