Problem with polar_coordinates()

[Lamas]

Bonsoir,

I found an elegant solution from Michael de Estrada :

// Conversion P-R
EXPORT pr(X,Y)
BEGIN
RETURN[X*COS(Y),X*SIN(Y)];
//RETURN(X*COS(Y),X*SIN(Y));
END;

// Conversion R-P
EXPORT rp(X,Y)
BEGIN
RETURN[ABS((X,Y)),ARG((X,Y)) MOD 360];
//RETURN(ABS((X,Y)),ARG((X,Y)) MOD 360);
END;

Thanks a lot for your attention.
